Default Polycrylic vs epoxy for glass cloth finishing

I would like to hear from users of both epoxy, and polycrylic in applying .75 oz glass cloth over wood...fuse, wings, etc etc. I am hearing that the bonding is better with epoxy...although the cost is much greater, and the application a bit more troublesome. I have used the polycrylic and found it to be extremely easy to work with, and although I have had no problems with it, I wonder if I am gaining the desired structural integrity with it. The polycrylic, being a water based product goes on much more easily, because it's consistency is thinner than epoxy, and of course it wets out the glass cloth thoroughly and quite quickly. Clean up is no problem...just rinse out the brush in water. Polycrylic is useable right out of the can...no mixing..no pot-life to be concerned with. I actually like it a lot, but would appreciate hearing from others with their pros and cons.
