Wireless controller - Bluetooth vs. Wireless Adapter

I think bluetooth is better.

I prefer a wired controller, but with the wireless connection, blue-tooth is a good technology. However if you have a bunch of blue-tooth devices in the same room there can be some connection issues between them.

I play with cable but bluetooth works fine.

I to use Bluetooth as my connection and haven't had any trouble so far.

I would choose the Bluetooth connection if I were you, adapters work but rarely have problems
