No Limit vs Limit

[mmbapmashida]

Sorry if there has already been a post on this, which I'm sure there has, but I found nothing through the search engine.

As I've been experimenting with Limit HE as of late, I was wondering what the main differences for cash games are...like, wouldn't NL be much more profitable? I see most players at around 10BB/100, and some even 15-20BB/100, which in this case is big blinds, but for limit I see the best winrates around 2BB/100 or 4 big blinds. NL seems more profitable, am I completely wrong in my thinking? These are just ideas I have, not what I truely beleive..
