it's tougher to outplay two players with a mediocre holding

I disagree. Look at the relative position of the original PFR. Assuming they both check as often will be the case, he has to act after me and before the loose player on the flop and the turn. He'd be less inclined to showdown unimproved big aces and he's forced to checkraise all of his moderate/vulnerable holdings.
