I have never heard of a transmission fixed with the new 5th gear (documented) that has developed the problem again, and looking at the redesigned part would help show why. In my opinion it fixes the problem completely, and the transmission should easily outlast the life of the car if repaired with the new part.
I've also heard the claim that the "fix" was instituted by Nissan with the '94 and newer transmissions so they should not "pop-out" in the first place. Utter and complete crap, as evidenced by the OP's '96 B14 having the issue. Nothing like a band-aid on a compound fracture, thanks Nissan.
You can certainly go with Bens advice, most folks seem to do OK with the "fix." It is the documented and "proper" fix. Ben can also take apart and put back together a tranny, so my personal experiences my be skewed.
Whatever you do, I recommend you also get upgraded motor/tranny mounts (Prothanes), use Redline fluid, and get an Andreas Miko Tranny-Saver Bracket.

On any future B13's I may own, the second the tranny starts to hiccup, it is getting replaced with a B15/P11 tranny. I will no longer even entertain the idea of "fixing" the problematic B13/B14 trannies.
