It looks like at the very least he recognizes Frieza was the pinnacle of his villains, in terms of buildup, characterization, and definable threat. Everybody else just felt like an asspull.
I thought Cell was pretty good, especially when they reveal he went back into larvae form and came from another timeline that wasn't the same as Future Trunks'. You don't see two time travellers end up in the same time period all that often in fiction. Closest thing is the Terminator movies, and the characters in that are from the same timeline.
I think it's more like he forgot about Cell entirely. Post-SSJ2 treatment of Gohan's character shows as much.
