Although I can't compare it to other brands, I've had nothing but good experiences with RAKA. I think the only drawback you may hear from people on this board will be that it's quite a bit thinner than other brands and that it has more tendency to run. But if that's the price for what's probably the best wet-out epoxy (because it's so thin) then that's a risk I'm gonna take.
I've used the 127 resin with both fast hardener and their 350 non-blush hardener. Sam McFadden didn't like the 350 hardener, but I think his test sample was on RAKA's 5oz cloth (known to be somewhat difficult to wet-out).
Hopefully Sam's out there, because I don't remember the difficulties he encountered.

All in all, GREAT epoxy, GREAT price.
