Tron is probably my most magical pin, I mean when I play it it's pure magic (IM is close) however if I had to pick a flaw of Tron and someone said it as well, the right side of the PF is weak. It's not much just the scoop and the pop bumper/loop shot and I really don't go for the right loop shot much it's not called for as you can hit Gem better from the Quarra loop which is called for so the right side is weak.
While XM (reverse Tron) has the same scoop and pop bumper/loop shot it also has Wolverine bash toy making the entire PF of XM from right to center to left have good things to do.
I think Tron is missing the second forward ramp (as we see with ST and SM it is possible to have three ramps for 3 flippers). Or like IM or AcDc 2 ramps for 2 main flippers. I think it would be nice someday if Borg revisits this layout to add another ramp, even a mini ramp like Jack the monkey ramp from PotC in place of Wolverine bash toy.
I know XMLE only has 2 ramps but it does have the moving ramp to add variation, plus Xavier up kicker returns via the side ramp. I think Borg didn't simply want to reverse Tron and probably added another target to shoot on the opposite side. But how good or bad that target is Wolverine is open to debate, it certainly could have been smaller.
