Music theory Nerds! What is the best musical key?

I have always enjoyed the key of E minor. When playing all of Andrea Segovia's scales from his book of scales, E minor was the most enjoyable regarding jumping positions. It was easier to develop a clean alternate picking style when using Segovia's E minor scale. I used to play drums when I was a toddler. Ho Ho! The technique I used with the drum stick in my right hand was later applied in a percussive manner with my right handed alternate picking technique on the guitar. Especially using the E minor scale and lifting my right hand completely from the strings however without using the forearm. I developed this way of playing and it proved to be successfully powerful whenever I performed fusion pieces. A strange psychological method to use when you are about to take on a fusion solo, is to imagine you are in a straight jacket. When the time arrives for your improv, you release yourself from the straight jacket and your hands are free with endless possibilities. It was a helpful tip for me when I mastered John McLaughlin solos.

Eh that was a poor one.
Anyway, never got around memorizing anything about keys, but my preference goes to Arabian scales. Don't know how they correspond to Western keys though.

I'm doing a music degree

but my mind does a flip flop from piano which ive played since i was 6 and guitar. i think diferent keys sound better on different instruments and are definitely used more/less based on what instrument the piece is written for.
