The scope I use most is our 3.5" Mak. grab& go,because it affords the quickest set up time.

The scope used the least, unfortunately, is our 7" Mak., because of size and setup time; this will change whenthe new permanent observatory to house it has been built,then it willbe ourmost used telescope.

Setup time for observing opportunities is the main reason,due torapidly changing weather conditions at my location.

My C8 on AVX mount, simply because that's my only scope.
Setup is a bit too long and in winter, thermal equilibrium is hard and long to reach. Field of view is also a bit too limitted so I plan to buy a light 4" triplet apo and a manual alt-az mount. It will most likely become my most often used scope but when I'll serup the C8, it will be for longer observing sessions.
I also like my Orion resolux 15x70 bino but that doesn't count as a scope (and I can't really enjoy it from home in my red zone).

Pretty much the same as Bill P. said. The 4" fract is on a nice AZ mount right in the kitchen next to my patio. Easy in and out. Alos I have it set-up that I can use my binoviewer in it at native focal length, no barlows. This scope replaced my ED80 as my grab 'n go, but still use it the a now power wide angle eyepiece to cruise the Milky Way.

Next used scope is my Meade LS-8 computerized scope when I want to knock off a bunch od DSO's without having to hunt them down, just push a button!

Least used scope has been my 10" Dob because of the weight. I have a bad back and need my neighbor to help me carry it out. Will use the big light bucket a little more this fall with a lot of DSO's out that I need the light gathering power and wider FOV. The double cluster looks great in it with my 34mm SWA and the Veil with a filter.

Lastly is my lost ETX-125.....forgot all about it with all the other scopes I have. Probably need to sell it. Oh, bino's are Always out with me!

For me, it has to be the 100mm on an alt-az mount. It's so quick and easy to set up that it's worth it even for a 20-30 minute viewing session. A close 2nd would have to be the Canon 10x42 IS binocs.

Hopefully in a year or two, I'll be able to set up a simple observatory and have the C14 permantly mounted.

Went through my logbook for last 5 years. Here are the percentage use of my telescopes:

Telementor: 29% (was out 103x)
ATC82: 21%
AS80: 16%
AS110: 9%
Other refractors:  21% (mostly Baader 95mm, ED100, Vixen 130SS, or triedr 8x40)
Mirrors: 4%

So in my case, there is a clear corelation between size and usage. Telementor with its 63mm gets the most of use.
ATC82 is long oil doublet of my own design. I had it only sice 2014, and during 2016 it was on loan (I got in exchange Baader 95mm triplet). If it was not for these, it would be my most used lens. For example, this year it got 67%.

Anyway, if I sum up all 80mm class refractors, I get to 37%. So 80mm refractors are winners in my case. Most of the sessions with these 80mm refractors are short planetary session (Jupiter). The aperture is enough to see interesting level of detail. Yet it is so convenient in winter (where most of the planetary session happened to be), always ready to be used on short notice.

My largest refractor, AS110, gets far less use. I'm using it in my darker-side observatory shed. Here I go only when the sky is absolutely clear, and I'm not tired, which happens less and less with three kids...

ST80 with new focuser on my eq2.  Simple, good 'nuff.  Next would be my C80ED on the same mount.  My 8" SCT is jealous, as is my old RV6 and 120ST..  I'm old, achy,and lazy, and more into clusters and starfields these days, although the 120ST is good for that, but it's a tad heavy and I never got a proper mount for it.
I'm also primarily back to 1-1/4" format with Plossls and one 8mm TMB. 
Gets the job done and makes me smile

As for the correlation between size and frequency of use, I suspect that has as much to do with non-optimal mount options as it does with any inherent lack of convenience afflicting larger OTAs. GOTO mounts in general and EQ mounts in particular require more set-up time. It really is no harder to put a 10" SCT OTA on such a mount as it is a 80mm refractor. What gives the refractor the illusion of being so much more convenient is the fact that you can put it on a simple, manual, entirely mechanical alt-az mount, that could NOT handle a larger payload like a 10" SCT.

But there's a relatively simple fix for that, and it dispels the illusion quickly - get a larger, simple, manual, entirely mechanical alt-az mount that is capable of handling larger payloads. I have a bunch of them: Takahashi Teegul Lapides alt-az, Desert Sky Astro DSV-1, Giro Ercole and AYO Master. The Giro Ercole is no harder to move around and set up than the two smaller mount heads; all three work happily on the same tripod. Unlike the wimpy Tak and DSV mount heads, though, you could pretty easily get away with a C6 or C8 and maybe a 6" MCT OTA, and certainly a 4" or smaller refractor OTA, including longer tubed options, on the Ercole.

The AYO Master is in another league. It's massive (weighs about 40#) and capable (figure a C11 payload would be fine), but also not very hard to move around and trivially easy (identical actually) to set up just like puny alt-az mounts. It even has a machined aluminum handle that lets you carry the mount head like a briefcase out to the tripod.

These days the only reason I field a 3" refractor on an alt-az mount is because I like to experience a 3" refractor experience. It's no longer because the 3" refractor is easier to set-up.

Best,

Jim

Currently my most used telescope is a 6-inch f/6.5 achromat -- due to its newness and convenience of use. Binoculars and other telescopes get 'tossed in' from time to time; but I still have (at least) one more project for the 6-inch that I want to complete before I settle back in with my 'primary' telescope. So the 6-inch will remain as the most used for a bit longer . . .

Least used is a toss-up between my larger Newtonians. For most things, I've found that I don't need (nor desire) the additional aperture.
