If you like more structured milsim style play I know Ricochet is trying to setup SWATT Vancouver but other than that I'm kind of out of touch with what's happening in Vancouver lately. However I think you'll need an AR when you get into it and roll with them at sims, if you're just a casual member you should be fine with whatever.
As for AK's, if you want a good starter the CYMA AK's (or Echo1 which rebrand the CYMA's) are one of the better starter ones, you can either upgrade down the road or buy something better when/if you want to take the next step.
On the AR side of things King Arms and JG are IMO good starters but G&G Combat Machine is a good choice as well (even if it is a plastic body....) better would be the G&G regular or Toptech line.
