I'll give you an example, not to bash against 3M nor anyone who love 'em
I do few stainless tankers every years for a client so I decided to try their SLS which claim to be especially made for this surface. Got a 10yds and printed 2 sets of decals (with 8518 gloss laminate). 5 years later when I compare the regular 180 with the SLS, and also those I made with Oracal 3951GRA/290G or Avery 1105EZ/1060Z, it's all identical. Few nicks due to high pressure washing, lost of like 15-20% of gloss, printed colors remain the same but variations from tank to tank is more a profiling issue (I'm probably the only one to notice it, client never complain 'bout it). The one I'll be doing next week will be printed on Oracal 3751GPS/290G and I'm confident it will stand the test of time as other did. I use few 3M products for specific reasons or simply because this roll doesn't cost more than competition's (i.e. IJ39 HiTack). I've tried Arlon equivalent after the salesrep pushed me to use it claiming it was the same as IJ39... NOT. 3M's is more dimensionnaly stable. Arlon's shrinked badly (more than 1/16" on edge) and the adhesive is all over the heated plate on plotter. Real mess to clean and manipulate. Price-wise they were pretty pretty close so no way I'm gonna buy this shit again.
For some colors in plotter vinyls, the 3M is the choice even if it cost more but my inventory is mostly Oracal's 751 serie (8 years cast), few KPMF, few Avery.
I do a lot of semis, never had comebacks (so rarely and anyway mostly due to abuse at weekly cleaning with 3000psi hot water...).
