Depends on the OP. Sitting down with just a few highly aggressive experienced opponents at a cash table will bleed you blind (pun intended). However the
odds are much more favorable, so fewer players are prefered if getting to see the flop more often and not getting pushed out after first bet or if your better than me and can stand toe to toe with really good aggressive players. Having more players creates more unknown variables. Good players understand this so it chills them out a bit. You also get more
hands in-between blinds allowing more chances for hands worthy of 3 betting without having to pay blinds.
