I feel you OP; I bought my JPPrem NIB 6 months ago, loved it for the first two days, then hated it for 5.5 months; now it's clicking and I am loving it.
It is definitely the TSPP of this gen, many more shots than TSPP though, that top right flipper is so satisfying, that's what really keeps me coming back.
It does have to be leveled correctly for all the shots to really flow IMO; and definitely not an easy shooting pin.
