Would you go for the S5, LG G3, M8.
My initial thoughts are S5, but looking to hear some feed back. Battery life is very important to me and having the ability to change them out is kinda important to me too, so M8 loses some points there. (although pocket chargers could work)
Also, best tablet to watch shows/movies(streamed off of sites like tubeplus) and just browsing the web?
