Go for the Lumia 735. The Lumia 925 has poor battery...I should know I own one. Camera wise I think the Lumia 735 has the edge because the front camera is way better. I'm seeing pictures posted on this forums - shots taken by Lumia 735 using the main camera and it is really good and sharp. The Lumia 735 has the advantage of Denim firmware, removable back covers, wireless charging by default (the Lumia 730 dual sim does not have wireless charging), SD card support up to 128GB. The lack of camera button is really not a deal breaker for me as I rarely use it. The amoled screen on Lumia 735 is good as well. I would suggest Lumia 735.
