Any of the guns you mentioned should work just fine. You won't need 3" shells for doves or quail, so the Rem 1100 will work just as well as the other two.
I like the Beretta 390 a lot. Very reliable, sturdy, shoots almost any kind of shells without balking. It will go a considerable time between cleanings.
The Rem 1100 is good also. Reliable, but not quite as sturdy for really long term use as the 390 IMO. However, the few parts that might break are inexpensive, readily available, and easy to replace. The 1100 needs cleaning a little more often than the 390.
So really, it's a tossup, but if I were buying it primarily for clays shooting, I'd buy the 390.
