Canton GLE 490.2 8" vs kef r 500 vs kef 550

I am updating my front speakers. I have a yamaha 780. I am trying to find someone whom can comment on how the Canton compare to Kef. and if any can be driven by the yamaha for 50/50 music to movies. My room is 14’ by 16’ living room with an 8’ (diagonal ) opening at one of the corners where the left side speaker would go to a 10’ by 10’ room. If anyone can help me decide I would appreciate it.
