1/4" - SK roundhead, 40970 (came with my 1/4" drive super set from ~12 years ago)
3/8" Koken 3725Z short handle
3/8" KTC BRSW3L roto ratchet long handle
Snap-On SL80A 1/2"
The Snap-On because it's the smoothest, lowest backdrag action in the strongest 1/2" long handled ratchet I could lay my hands on. Incredibly, it ties for the lowest backdrag of
any ratchet I own with the little SK 1/4" shown, which both have even less backdrag than the pictured Koken. The Koken 3725Z is light in backdrag and equals that of the KTC roto ratchet shown. I choose either one depending on if I need a short or long handle.
