Ok, i'll overdo this reply slightly, just to try and bring some balance to the force....
You clearly liked your G5, do what you think rather than listening to others who may not own the device. Although there is a lot of noise around this phone, if you look at the threads with real owners on, the vast majority got good quality phones, with no issues, and are very happy with them. These tend to be one liners, whereas the negativity is repeated a lot, so looks bigger than it is. If you get another one, it could and should be perfectly fine. If you are putting a case on it, then nicking it should be less of an issue (I can see how the painted thing, will make it more susceptible to knocks).
Also, if you liked the wide angle camera, the HTC can't give you that, the G5 can, and is a USP that no-one else has right now. Likewise, IR blaster, removable battery, on screen buttons (my personal preference), fingerprint sensor on the back (preference) - if you like any of these features, then the G5 gives it to you. Or maybe you don't like antennae lines, which LG have very cleverly covered up - the first metal bodied phone to do that. I bet they wish they hadn't bothered now.
So... as I said, do what feels right for you. Don't just get an HTC because people have told you to, do it because you think its the right phone for you and you prefer its features over the G5s. Which other than a slightly better camera, and the feel of cold hard metal against your skin - which apparently is all the rage these days - i'm not sure what the 10's standout features are. Still a good phone, don't get me wrong.
And just being facetious for a second, one of the early criticisms was this whole cold metal thing. If that's such a nice feeling, why don't case manufacturers make cold metal cases to put on your phone? Maybe, its because its not a very welcoming feeling. LGs primer on metal gives you the best of both worlds, premium metal, without the harshness.
So as I said, this isn't meant to be taken too seriously, but this is about as overly positive, as some of the overly negative posts are, just to balance things up.
Seeing someone get talked out of a phone she clearly really liked so easily, made me feel a little bit sad inside. 1st post "I'm loving this phone...". 2nd and 3rd posts - "get the HTC 10, get the HTC 10....." - "Oh ok then".
