I was looking at pretty much the same phones. (not the style as it was more expensive)
I went with the LG G4. In terms of specs, its much better than the Play. Faster processor, more RAM, and double ROM. Yes the Play does have a bigger battery but many reviews on it have suggested it isnt that efficient with it so you dont get much more time with it anyway.. I get easily over a day with my G4 and I use it a lot.
For a very similar price the LG was worth it for the nicer specs, and the screen and camera are fantastic. The buttons on the back are odd to start with but it really does work. and Its got the funky ‘double tap to wake’, it now annoys me when using other phones that i have to push the button.
It also charges super quick, and comes with a really nice set of earphones.
Ive got mine in an otterbox defender case which feels bombproof, but if you will be wanting to put it in a case, don’t get the leather one, the extra thickness wont fit in most cases.
I got mine on ebuyer for £270
