Alas, we don't have much choice these days. I loved the fact that I could just dump the battery if the device misbehaved. And putting big fat batteries in that would last... Sigh....
I used the LG G4. Now I have the Nexus 6P as daily driver and Nexus 6 and 5x as backup. Don't really regret not having a removable battery. I only charge to ~80 and don't discharge much below 30. My 6P battery is still at 99% capacity.
