Just like nearly everything in the hobby, when it comes to degradation, there's multiple factors involved. One person's experience is never really indicative of what's going to happen with everyone. Like pleather for instance, I've nearly never had that issue of them cracking unless it was from a pre-owned figure I bought from someone else. Ones I've personally purchased are still look as good since they day I bought them with the one exception of HT ANH Han Solo boots. I've been using Phicen/TBleague bodies since before they used the metal endo skeleton and even then, I had the plastic internal joints snapping, but never any cracking in the skin itself.
That said, it sort of surprises me how doing a bit of maintenance every now and then on these pretty expensive collectibles appears to be too much of a chore for some to do at least once a year. Are these the same ppl who can also never be bothered to wash their car or clean the inside every once in a while?
