In terms of comparison to the real tables, the TPA version of ST:TNG is by far the most accurate. My real high score and my TPA high score are nearly in a 1:1 ratio. Most tables it's 10:1 or higher in favor of TPA.
In terms of relative difficulty compared to the other TPA tables, ST:TNG is too hard. RBION, MM and TZ should be the three most difficult tables released so far. The first two are where they should be compared to the rest of the tables; TZ is still a shadow of its true self, although the removal of that barrier in the bumpers will help matters some.
EDIT: I suppose I should answer the original question while I'm at it. I don't necessarily regret buying any of the tables, but Harley Davidson is really close to falling in that category. I don't care much for Black Knight either, although I appreciate its historical value.
I think MM is the hardest one for me, but I never got good at the real thing either.
On topic; I don´t regret buying any table but HD & BK gets played the least and Genie is really getting on my nerves, just can't get a decent score on that one.
