I was interested to see this thread here. I am struggling with the same decision. I have had my G3 since launch and received my OPO about 2 weeks ago. I have used the G3 as my daily driver for several months, and have been using the OPO for 2 weeks now as my daily phone.
To me, the G3 has some advantages:
* I prefer its form factor and in hand feel of the G3 to the OPO. Its much smaller than the OPO with the same 5.5 inch screen size. Being more narrow and a bit more rounded feels much better to me. I also like the back better. I am not a fan of the sandstone back and wish there was a way to get a replacement. I never use a case on any of my phones. This is a big one for me- may not be for other people.
* The G3 screen is far superior to the OPO. I am not talking about specs, but the side to side look of the screens. The G3 is much more vibrant and a bit clearer. I don't have the yellowing problem on my OPO so I can't comment on that. This is not to say the OPO screen is not good, but side by side to the G3 it seems washed out.
* I like having the option of a replaceable battery on the G3. I travel sometimes and this is very handy.
* The camera seems to be better on the G3, but both cameras are faily good so this is not a huge factor for me.
The G3, however, has one major issue that I can't seem to get around. When I load it up with my daily use email, social and other apps, it gets unreliable. It often overheats and will randomly reboot. I have reset the device several times and even had a replacement sent from AT&T but it still is not reliable. I thought initially it might be the screen that was causing the issue, but the phone runs flawlessly for days on a charge with the SIM card out with only WIFI connected. Maybe its the radio, I don't know, but not being reliable is is a pretty big negative.
The OPO on the other hand has been rock solid for the 2 weeks I have been using it. I miss the in hand feel and smaller size of the G3 even after trying to adjust to the OPO.
The OPO also has some additiona strengths over the G3 I should list:
* Fast, reliable software. The G3 launcher is noticeably laggy. This can be fixed somewhat with ApexLauncher or some other launcher, but I still think these run slower on the QHD screen.
* Value for the money. Cost is not a big issue for me, but if it is for you then the OPO is the clear choice.
* The battery life is very good and very consistent. I can always count on it to act predictably. The G3 was the opposite. It would start to heat up suddenly and in an hour it would tear through half the battery even while off in my pocket.
* Software updates do not have to go through the carrier. I am thinking this phone will get Android L long before the AT&T G3.
All in all, a tough choice. If the G3 worked predictably for me, I would probably choose it because of its better screen, form factor, and slightly better camera. But unless I can figure out this heat up, reboot, and battery drain issues, the OPO is looking like the choice for my daily driver. I will probably keep both for a while and tinker around with the G3 to see if I can figure out why it is so unreliable.
