I haven't played Rivals, I do not intend to either since mobile games are not my thing. Phones are for calling people, for everything else I use my PC. #OldPeople?
But if you compare TA to Rivals on paper then out of two shallow games there can only be one "winner", and TA would currently win this simply based on still having some actual strategy components - which of course got mostly trimmed down to make monetization work, but oh well. Oh, and Rivals has gambling boxes. Fuck gambling boxes.
Actually, YES EA ADD GAMBLING BOXES! The more the better; Add enough and your game is triggering new EU laws against this predatory practice. I would not weep if they were not allowed to launch this pile of cash grabbing horse shit in the EU.
