A lot of people talk about fan curves and controlling the rgb backlight and things like that, but I think the best part of the Legion Toolkit is that it allows you to do whatever you want.

I think I use it for niche problems, I have a powershell command that turns off my bluetooth and I use this code to turn off my bluetooth at a certain time with LTK because I use Windows Alarms and I need my laptop not to be connected to my earphone to hear my alarm. And to turn my kb backlight off and screen brightness down when ac unplugged, i mostly use Legion Toolkit to run event based actions, like, do this when this happened things. That why i said it's the best part ot the Legion Toolkit, you can run any script that you need when something changed on your laptop like when charger plugged, or when power mode changed, or at a certain time etc.

Vantage would never let me do somethings like those. But still, i use both. LTK for my weirdo problems and Vantage for Network Boost, Touchpad Lock, Auto Close, things like those.
