It's only my opinion, I agree it's too early to say for sure. Although, it's not like Martinez has been great for years either.
Martinez is a really good keeper, like you say, his penalty stopping is top notch and he has great handling. I really like the command he has of his area too - an area I would say he his comfortably the best in the League at. But I also think he lets too many shots in that he shouldn't. Even last year for Villa where he was very good, behind a very defensive team that kept him well protected - he let in some really bad ones that went largely without criticism (let's be honest, mainly because no one really care about Villa outside of Villa). I'll be disappointed if Ramsdale doesn't have him beat there, and I think he does. And I think Ramsdale has him well beat on the distribution front as well, it's not close. And that's not because Martinez isn't good there, it's the our guy is exceptional.
Ask yourself, would you swap them tomorrow if you could? I definitely wouldn't, and I reckon even Meatwad, Martinez's biggest fan (and I honestly was not far behind him), would have to really think about it.
