I am one of those people who do not like the factory cassette options. So much so that the only bike I have with an actual cassette is my winter snow and ice road bike which has an old Shimano XTR 11-34 9 speed cassette on it. For example, on a double chainring road bike I want 11-13-14-15-16-17-18-19... There is zero desire for the 12. A triple might use 11-12-13-14-15-16-17-18-20-22-25, but that again is not a cassette.
So whatever close ratio cassette the manufacturers sell, I will not buy, and using those sales will not work as market research. Also now that I change chains when the Park chain guage hits 1.0, I get at least 4 chains per cogset, which on the dry bikes is 3k miles per chain and 12k miles per cogset, and at 6k miles per year and 5 front-line bikes that is not a lot of cog swapping due to wear.
I use shimano freehub compatible cogsets made from Shimano Miche and Marchisio cogs. I use these on 9, 10, 11 and 12 speed setups with campagnolo and shimano shifters, both cable and di2/eps (although my eps setup is now in a box, not on a bike). I mix derailleur and shifter brand as needed; one of the best shifting bikes I have is my Ritchey Breakaway with Campagnolo 11 speed shifters and an SRAM Red 10 speed rear derailleur filed to tune the shift ratio and a shimano 105 front that came on the previous iteration of the bike. The SRAM Red was originally on the superlight bike, but it did not work with powercordz so it got moved over (the superlight now has one of those carbon-sports lightweight super-expensive out of production things).
Also I believe I also mentiond that I use things like 46-26 chainring pairs on several bikes, which also works quite well, assuming that you are not riding in a group and are willing to take the time needed to do the front shift and assuming you are NOT using shimano cable shifters and assuming you are willing to work on the shifting mechanics, both overshift prevention and upshift tuning. And also assuming you are willing to pay for cranks like Lightning, or make your own offset crank bolts to put small chainrings where they were not intended. And also assuming that you are not a 1000 watt person, who both does not need this and also will break stuff. And also maybe you need to have misspent your youth where your only bike was a braked fixed gear (with a brake you can go flat-out down hills where the rear wheel is hopping off the ground because your legs cannot keep up, and expect to keep riding without crashing).
I had a Zipp disk with 12 rear cogs at 11 speed spacing. (I have no power any more and the whole joy of a time trial bike is the speed, and with no power there is no speed, so that bike got disassembled to make space in the bike room for another bike I would actually ride. The Zipp disk meant that the complete bike would not hang from the garage ceiling.)
