To each their own, right? About the only thing I admire about PBT is its thickness/durability (which includes its resistance to yellowing over time). Dyesub will always be inferior to double- (and triple-) shot in my eyes. Plus, PBT tends to have a rather rough surface texture, and I prefer the smooth feel of semi-gloss/smooth-matte. Combine all that with the fact that you won't find SA-family keycaps in PBT and you have a material that has virtually nothing to offer me.Hypersphere wrote: ↑Moreover, the PBT is delightful to touch, and the dye sublimation is beautiful to behold.
I know that at least one vendor (is it Vortex?) out there has begun making PBT double-shots lately. If they were to provide SA-family double-shots with a smooth matte finish and a variety of colors like SP does, then they'd really have something worthy of my attention. Until then, PBT will continue to crawl way below my keycap radar (along with all the integrated keyboards out there that try to list PBT keycaps as a selling point).
