i find that the biggest difference is if you pay attention it will pay off for you more. you can make all the reads and put players on hands that you want for lower stakes but rarely does it actually pay off. at higher stakes players are normaly solid and you can trust your reads more. at these lower stakes players may play totally crazy one day and tight the next. but at higher stakes players play more consistently. this is nice if you pay attention bc it enables you to win more pots by just timing bets/raises well.
