I have a lot of tools (worked on fairly big equipment the last 30 years and a lot of it before that)
I never found most Snap On Tools any better (often worse - the combination wrench hurt my hands as they are thin ) than my JC Penny wrenches (got those with my first rig) - I have Sears wrenches for backups.
In a few cases, I found a tool that just felt good (or worked really well). I have a Snap on 3/8 Ratchet like that, a 10 inch Snap on Crescent wrench a fried gave me (well the 3/8 as well) and the Snap on Toque wrench in the dial type are to die for (they work so darned good)
The point is, just because it cost more does not make it better. I rate my RCBS and the one Forster die set as equal.
And expensive may indeed be better. Its really in the domain of the user. Is the function that much better, do they work that much better?
Some years back we bought a VW Passat (diesel). Mostly for the economy. My wife likes it because it drives and handles really nicely (not a hot rod sports car but solid). I have come to love that aspect as well (truck guy)
Forster has a much nicer and accurate dial on the seater than RCBS, but not so much a function as make the higher price offset for me but someone else may feel differently.
