I think it's better to check the Flop and see what happens. Given the description of your opponents, I'd probably stuck around by c/c all streets against the aggressive one (unless an A comes).

But I don't see a lot of value in betting out the flop (sometimes a weaker hand will call you, but you probably get more value and a better risk/reward ratio by checking). Checking also gives you a better idea of what SB might have. And if you are ahead, you probably don't need to protect your hand a lot, because if you are ahead villain(s) most likely have only 2-5-7 Outs.

As played, you bet-out this dry KJ-Board and got 2 Callers and at the turn one of them bet and the other guy also calls, I'd be done with the hand. They might be weak, but it's hard, even if they are, that not one will currently beat you. And even in this scenario, they will have 12 Outs against you or so. So, you might c/c the turn based on odds as they make it so cheap., but c/r seems to be a fancy play. Also, you can't represent here really a monster. KK/JJ would you have probably raised pf and even if not, there were no 3player action if you have those blockers in your hand. By c/r here, you represent KJ or Bottom-Set or a weak hand. The last one is the most likely, so your villains won't fold top-pair or AJ or so here IMHO.

But to outline it, I think it's much better to check the flop, probably call the aggressive one, but don't call 2 players and if you just don't want to gamble, just c/f like here already suggested.
