I love my Borg trio of Tron/Met pro/IM but I have to pick Met pro overall as I think it has a lot more rules than both IM and Tron plus IMO Met has better artwork and great music. I think the trio are all valid but pick Met pro as the top dog.
Next I'd like to have a very deep/complex rule pin so therefore I'd pick either Tspp or AcDc premium.
Last night I was playing WoZ RR edition and while it's still not my favorite pin, that edition is really boss and I think possibly in time it could grow on me. I dislike the single ramp, but overall think Woz has got a very interesting layout and the rules appear to be very nice now.
At this point I'm going to lean towards Tspp since it's rules and more interesting layout than AcDc.
