Systemas aren't anything massively special in stock form, certainly not range/accuracy wise; they don't perform impossible feats of physics defying-ness that no other AEG can perform. Its' highly debated and there are many arguments and defendants on both sides, some say the hop unit they use is a lot worse than your average V2 AEG, some say otherwise. Either way, the range and accuracy you'll get from a TM that's less than half the price of a PTW will certainly be at least very close, if not potentially much better. Not as good trigger response, but that can be improved on down the line if you really find the stock gun so lacking in that respect and use a lot of semi.
Plus you get blowback and recoil with a much more tactile bolt catch on the TM guns. Though PTWs do of course have that really easy quick swap cylinder which is nice.
The 416 is one of the best options for a recoil gun if you're shooting lefty; AFAIK it's the only AR style recoil gun with ambi selectors. Bolt release is only on the left side of the gun though and that can't be changed, not sure if any ambi mag releases will fit. The SCAR has ambi mag release, only 1 side for the bolt release. The G36s have no bolt catch/stop on empty and both the selectors and mag release are ambi.
