Experienced devs: Have you tried working with a mechanical (and/or custom) keyboard? Has it changed anything? Would it be worth investing in?

This question has been bouncing around my mind for a bit. Please let me know if I've accidentally copied the same question from someone else.

Alright, epic throwback to high school
-So I'm taking this CS course on java
-Teacher seems legit
-Knows his shit
-Gets the job done
-Introduces the class to an IDE
-Such wow
-I whip out my Eclipse Oxygen (with Hello World preloaded, obviously) like the nerd I am
-Suddenly:
-BlueJ
-Literally the worst editor ever
-And teacher somehow expects us to work in it with git

WTF.

For those of you who have never worked with BlueJ, thank God you haven't.

/end rant

What new languages should I learn? I'm working on C++, but PHP seems fun...
