so long as it automatically rolls I'm happy. My coworkers love the fact that they don't have to do a major operation every 6 months and instead its just part of the normal update cycle.
For gts vs latest, we are all on latest and so far haven't had any needs to go to gts because the kernel seems to be the same in each. GTS was handy when new releases came out for extensions and have an easy target when the dot release broke stuff. Have looked at trying to do ucore on desktop though for that slightly slower kernel.
