I owned the nexus 4 and currently own the moto x. While the 4 isn't the new nexus 5 they are similar in ways. I was in the same boat as you but on a different carrier. I seriously waited out the nexus announcement because that was the phone I wanted. Then it came and I wasn't as impressed as I thought I'd be. Yes it has a large screen and the newest os but that is all I can see that it has going for it. From what I read the battery is sub par, camera is mediocre and the design seems uninspired. [...]
Plus I heard the nexus has once again a crappy speaker... Ugh.
Please please please stop believing everything you hear and read, and especially giving comparison opinions based on things you read about phones you haven't used. I have owned the Nexus 4, and now the Nexus 5, and I can categorically say that the difference is fairly big. The screen is a lot crisper on the Nexus 5 - I didn't think it would make much of a difference either, until I actually got it and felt the difference. Video playback (YouTube, etc.) especially is gorgeous on the N5. The Nexus 5's battery is not "sub par." In fact, it is excellent. I don't know if it compares to the Moto X, as I don't own a Moto X, but it certainly is more than enough to take moderate to moderate-heavy usage and last an entire waking day.
The camera, the camera. The camera on the N5 in my experience has been fantastic, and much better than most of the reviews I read or hear. Photos are meant to be shared and preserved, and despite all the loud moaning about color saturation and white balance, the Nexus 5's photos are good looking, vivid, and fun to share. The OIS is a godsend. Despite having an 8MP camera, same as in the N4, the N5 camera's quality blows the N4's out of the water.
I have the nexus 5 and I am selling it for the x, which I ordered today. I like the nexus 5 but I miss the battery life of the x and the radio. I live in Salt Lake City and there is great LTE coverage, but with the nexus im in and out all day long. The battery is very subpar and connecting to wifi is horrible. I cannot connect to worth because the range of the nexus Sucks. Besides that the phone is solid, but the active notifications, always listening, build quality and assist puts this phone up on top IMHO. Now only if the wood backs were available.
I have no beef against the Moto X, and congrats on your new phone. However, it is possible that you simply had a faulty Nexus 5 unit. I have had no wifi issues or signal drops in known coverage areas for my carrier (T-Mobile).
Accurate color, proper DoF, quick auto-focus, lower ISO, better dynamic range, less noise. This is all because LG pays Sony and Kodak (and likely others) for their software to build a JPG from the RAW data. Google isn't keen on adding too much proprietary stuff, and wants you to use Google+ to "fix" your images. I don't blame them, but their decision shows.
Bingo, and this is why I don't think you can have a proper comparison of the picture quality without taking Google+ auto-enhance into account. My Nexus 5 takes what I think are great photos, but I don't even worry if one photo isn't so great at first, because I know Google will make it auto-awesome! The user experience spans that auto-awesome, and while that is not technically a property of the phone itself, it's something that deserves consideration in reviews, because to the user, it really doesn't matter if a software on the phone is doing the enhancing or something on the web.
