Terrell Owens says he'd take Carson Wentz over Donovan McNabb -- and he doesn't give a damn what his former quarterback thinks about it.

We got T.O. out in Beverly Grove ... and asked the former Eagles wideout to pick between the Eagles superstar QBs.

It was a tough call for Terrell, but ultimately -- "I'd probably go with Carson Wentz."

Owens says he ain't dissin' Donovan ... telling TMZ Sports Wentz is just that good.
