Is UNET a good choice for a competitive multiplayer game?

I’m working on a competitive multiplayer game. Some matches will be 5v5 competitive, others may be 10v10 or 20v20. My question is, is UNET good for this? I read somewhere recently that Photon is better but more expensive. I’m on a tight budget, and I want to make sure that if I put time into learning UNET and making a game, that it will actually run well and perform well. Also, I would have to buy access to Unity Servers, which is fine. I just want to make sure that using UNET and using Unity servers has good enough performance for a competitive FPS.

Thanks.

I would go with Forge server for a competitive game.

Note that its very efficient, very fast but lacks huge amounts of players. 20 max per match I would say.
