I'd love to give you a fair view on both, but I'm biased to battrick, both games took me two attempts to continue playing, I've been playing battrick since 2005 I think -second time-, FTP since last year -second time-. The thing about FTP that really annoys me is the training, mostly because you can only train one thing at a time, whereas with battrick although you only get 10 coaching sessions you can mix and match with nets to improve various skills at varying speeds.
Also with battrick, unlike FTP you don't get a youth and senior squad, but you do get first class matches (3 days).
That's about the best I can do, all I do is log-in once a week to pull youths and make sure I'm training my best players.
