General Finishes new Enduro-Var vs Arm-R-Seal

couple of weeks ago I read some info about General Finishes new Enduro-Var Urethane Varnish. From the GF website: Enduro-Var is a self crosslinking polyurethane that looks more like an oil varnish than a water coating. It ambers slightly, is our most durable coating, is highly water resistance, and is both sprayable and brushable. It is our top of the line coating and should be used when you need the very best. Suitable for floors, cabinets and millwork.

I had to give it a shot and compare it with their old standby Arm-R-Seal which is an oil based varnish.
