Is Infinity beating Warhammer 40k on aestetics?

Hi I'll start off by saying this isn't a GW bash post, but a simple question. I have played 40K for many years up to 5th ed and a couple of 6th ed. I'm not the best of gamers, but I did enjoy going to the odd tourny as a fun thing. My point is its the looks that draw me to a game, not the rules. Obviously the game has to be good as well for me to continue investment! I'll even pick a dud army
