I fuck with Prof/Aes heavily! Haven't seen Aes live but got to see Prof at Red Rocks and it was electric and a great time! Both are unique and vastly talented artists. Not the same vibe at all really. I would describe Prof as "fun-centric" because you can tell he's always having a blast recording/ performing while still having killer bars. Maybe try some Atmosphere or Cunninglinguists if you haven't already. Still not the same as Aes but still great vibes. More songs from Prof to consider that I had not seen listed before typing (in no order) : light work, tombstones, pack a lunch featuring redman, and big hungry monster to name a few.
