I'm a gear whore, so I've got a dozen different pair of wraps to play around with, and I can give my bits on a few of them.
Everlast Mexican Style 180 wraps are my favorite. They're good and thick, with a quality enclosure and a real nice weave. They stretch well and keep tight. The thumb strap on them is just right.
Everlast Cotton 120 wraps are probably my second least favorite. They're thinner, no stretch, crappy thumb loop and they're kind of heavy. They last fairly well though, and they roll up nicely. I think any wraps at 120" are way, way to short though. My hands aren't giant, but they're not small. I'd prefer something like a 210", but nobody makes it, that i Know of.
Title Platinum Hand wraps: these are the my least favorite I've used. They're 160s, so the size is okay, but they're wicked uncomfortable. The site says they're "just slightly stretchy" and that is a load of shit. These things feel like cardboard wrapped around my knuck's. They lay flat and heavy, and don't really form to your hand, like even cheap cotton wraps do. I really dig the line down the middle of these, and the hook and loop is pretty good. The thumb loop is kinda crappy, but the weave is pretty nice.
Title Classic Mexican wraps: These are actually really nice, but they're only 160s. If they were 180" i'd probably buy a lot of these. They're not super-tough though, so they won't last as long as, say, the Everlast Mexicans.
Title Mexican Style hand wraps: These are like a cheap-ish version of the Everlast Mexicans. They're 180 and a nice thumb loop. The hook-and-loop is kinda odd though: it's a lot bigger than all the others on my list, and I'm not sure I like it as much. The weave isn't quite a good as the Everlasts, and they probably won't last as long. Still, these are the second best type I have.
I'm going to order some of the Bad Boys, Warriors and Rival wraps. Hopefully they're at least as good as the Everlast ones, as they're more expensive.
