The Logi Options app does seem pretty solid and it gets updated regularly - actually almost annoyingly frequent updates (which require you to uncheck sending analytics every time even though it was unchecked pre-upgrade).
I did run into problems when running Options alongside Karabiner Elements (my primary use: make Caps Lock a “hyper key”).
While the hyper key remap worked fine, many of the other special function keys (brightness, media control, etc.) were scrambled. Using the built-in Karabiner utilities it looked like the Logitech was outputting some non-standard codes. Not sure if that was due to a conflict between the two apps or what but those keys worked better, though not 100%, when Options wasn’t installed. (Hard to give up the hyper key once you’ve used it for a bit!)
If you don’t need to use Karabiner, then ignore this post!
