Buds Pro or Others?

Im currently using the Buds+ and i love everything about it (comfort, fit, sound, battery life). However my brother gifted me a Buds Pro and im thinking to replace it due to many people saying that it does not fit well as it is bulky.

Im a casual user, so comfort/fit > battery life > sound quality. Should i replace the Buds Pro with Buds 2 or Buds 2 Pro? Or just sell it for cash and wait for newer release?
