Personally I was content with 3G, especially 3G voice that was part of 4G LTE until the US carriers were allowed to kill it and force everyone into churning devices. I would likely still be using my S7 if not for that.
I'm just saying as far as service level and amount of data on plans, I personally was content with 3G levels. There's so much advertising pushing us into churning for technolust incrementalist spec-chasing, that I find completely uncompelling as what really defines my devices' capabilities is software freedom.
