Are you in Europe? If so, I'd recommend the "Light Power Edition" version of the 5020. 1200 lumens in Eco mode and you'll be set.
If you're not in Europe, well it's a little tougher. The Epson will give you a bit over 16 fL on either screen, so that's just fine. After 500 hours on the bulb you'll be down to 12 fL or so. Still OK, but starting to get to the point where some people will want to replace the bulb. The Sony will give you 21.7 fL in Normal mode. Some people will find that too bright, but of course you can switch to ECO to drop output. After 500 hours you'll still be getting over 16 fL with the Sony.
The Sony is a good amount quieter than the Epson at full power. In ECO, they are both very quiet. If it were me, and I could not get the Light Power Edition Epson, I'd go with the Sony for 2D. If I could get the LPE, I'd get the Epson.
3D, well, that's more complicated. In the thread I link above there's a very good shoot out between the two projectors. I'd study that if I were you.
