I'm a HUGE fan of Superpump 250. I had to dial down to half a scoop because I was going bonkers in the gym. I can only compare it to Fast Twitch and some nitric oxide pills though, haven't used NO-Xplode. Superpump is more respected in the bodybuilding circles I've hung in.
ON 100% Whey is a great deal for what you're getting - mostly protein isolates. 10 pounds at a time will yield you almost 49 grams of protein per dollar, better than most. This site sorts proteins by grams of protein per dollar, most of the ones above ON are Whey CONCENTRATES though, which aren't as good as isolate:

But All The Whey's one might be a better deal, and it's PURE isolate. Never tried it though.
