I still use the 1000 and 1200 in gray and 1500 in black as primer but seldom use the 500 for filler, I always had issues with bubbles on the 500 and found it harder to sand than the Bondo spot putty I use almost exclusively these days. The spot putty is easy to smooth and contour with a cotton bud and acetone based nail polish remover. While that can be done with 500 I always get quicker and better results with spot putty.

I use it on occasion for small fills. Also utilized it for the non-skid on my SH-60 build.
