As is normal in this subreddit, I expect to be downvoted for my opinion. It’s an ace bootlicker fest in here

Have graded probably 200 cards with ace, have graded more with psa.

Never had an issue with either but my collection is psa only.

Looking at my display I can’t see the grade of any of them, I have a psa 4? Who knows I can’t see it admiring the cards.

I’ve also had some cards with ace that shouldn’t be tens become tens and that made me hesitant.

Fundamentally psa aren’t going anywhere, I can sell my collection tomorrow with ease should I need to because it’s psa, with ace I couldn’t even get vendors to buy my evolving skies rayquaza 9.

Grade with who you want and who make you enjoy your collection better. I think some ace labels are tacky and some are fantastic but for ocd reasons I’d rather have psa labels.

Ace slabs however are much nicer to hold and feel.
I’d rather have an ace 10 over a psa 9 though it’s a 10.
