Kernel questions will always cause some discussions. To make it clear: I am not the one who can decide the subject. In my experience "linux-generic-hwe-16.04" installed via Synaptic works fine and gets regular updates (security fixes and some backported stuff here and then). Right now its 184.108.40.206.35.
"Linux-generic-hwe-16.04-edge" would have installed the 4.11-series. Quite new hardware might be supported better.
As Jeff has pointed out there is no desperate need for desktop users to change a working Kernel immediately if something new is offered. Other things enhance security. To all whom it may concern: Things like WebkitGTK+ should be more frequently updated (at least 2.16.6), or libsoup (should be 2.58.2).
