I'm not more experienced and certainly not wiser, but my son is 14u 2023. He plays as much 2023, 15u, and even 16u as he can, but will jump in a 14u tournament for fun if there is good competition. The most recent one the tournament zeroed in on him and did a lot of Twitter and video stuff on him. He would not have had that had he been in the 15u or older division.
