I had my choice, and chose Pro and would do so again today.
The difference to me is about speed. I like really fast games. To me, the hammer and snake jaw slow things down a bit. I know some othss who feel the same as me and got the Pro. I don't so much care about light shows, I care more about how a game plays, so that didn't factor for me.
That isn't knocking anyone who likes the Prem more. If you're into looks and cool mechs, I would agree it wins. For the specific game play I like, it's pro all day.
