They're cut like a "regular" shirt, rather than with extra length, etc. so they may or may not be suitable for your purposes. You can compare a size chart to see if they have the length you require.
As for the quality... some people regard them as a "cheap" brand. They are often criticised for having oversized arms. That said... the quality is good if you're talking things like colourfastness, stitching, etc. They're not a thin, crappy shirt that will disintegrate after a few washes. I wouldn't say their durability is better or worse than any other similar major brand (i.e. Hanes, Fruit of the Loom, etc.).
Really the best thing to do is buy a sample or ten and try them for yourself. They're not expensive, and they are reasonable - so if you're interested you might as well check them to see if they meet your needs or not. If you're in the hip-hop market though (which it sounds like you are), I haven't really heard of them being used to get that oversized effect.
