Very, very broad strokes here........ but the bigger the jet..... the bigger the hours......... fighters small........ tankers and haulers, big.
Also, one other variable........ there are also guys in my reserve squadron, who are active. They can fly a ton. For the most part, all of us reserve guys are flying full time with an airline, so the active guys in our squadron have to pick up the slack to make missions happen.
I will say that those active duty slots in a reserve squadron (FTS) are very hard to come by.
for what it is worth,
