Similar experience here. I have them feeding a hub in the living room then splitting off to TV, consoles and Sky box.I don't know about "best" but I've been using a pair of TP-Link powerline adapters for over 3 years (so I can use ethernet on my living-room TV) and they have been solid as a rock, still using them and they have never given me any trouble.
But as long as you buy any of the big-name brands (TP-Link, Netgear etc) they should be fine.
