I have a lot of Jorgie (and off brand) f-style clamps in various sizes. They do get used by not near as much as my Bessy K-body and Uni-clamp styles. I have over a dozen pipe clamps that have been hanging on the same rack for almost 2 years. When you need them, they are the best but for me most of the time, they are stored.
In general I would say in order of frequency of use (meaning any time I grab one) I would say:
Bessy mighty-mini
4" and 6" f-style
18" - 24" Uni or K-body
6" Irwin Quick Grips
Larger Quick Grips
Longer K-body
Large f-style
Your mileage will most certainly vary.
