SPGX or BallistiX

[floatinghat]

I have narrowed my floor surface to SPGX or BallistiX. This is a 6mo old new slab, use will be a home garage shop, some wrenching. Wants are looks good, can repair damage, chemical resistant, not too slick when wet, reasonably easy install (diy), and if all equal cheaper is better. I have looked at a number of threads. I have in my prep process for each but would like to hear from those with experience.

Location is Pacific Northwest
