It makes no objective financial sense to go Premium over Pro. From a pure "value" standpoint (dollar to materials), go Pro.
I still like the Premium more though. The hyper loop ramp is a lot of fun. The death star ramp does add some extra difficulty, but I don't find a pin being more challenging to be a downside. I don't find it so much harder that it is frustrating to play, as long as it is adjusted so you don't get bounce back rejects.
I am biased though, I always tend towards the Premiums. If it helps I am an average player at best, don't enter tournaments, etc. so for me the personal fun factor outweighs most other considerations. If at all possible, play both before deciding. I didn't, there was a Pro locally that I played, but for Premium/LE I watched a lot of videos, asked some people whose tastes were similar to mine who had the LE what they thought and went from there. Don't regret it myself. YMMV.
