Invisiglass is available from JJP (exclusively? I think?) and is the best performing glass that doesn’t break the bank - PDI glass is held up by a lot of folks as “the best” but the price is expensive and the performance doesn’t seem to justify the expense IMO.
Stern’s HD glass is good, but as expected due to the price, it’s not perfect. It rejects notably fewer reflections from the dmd, which is probably to be expected, as I believe it’s only coated on one side. It’s still fine, just not “the best”.
I also have a sheet of AP’s magic glass and this works QUITE well. I’ve not compared it side by side but the playfield is crystal clear, and it’s on a Houdini which is a very bright game. I also installed it on my MB and saw (anecdotally) better performance than the Stern glass. Have not tried Voodoo
