Would it be best to do Boxing or Muay Thai?

[Shazam815]

This is not a which one is better debate or question, but I am asking which one should I learn first or a bit of. I learn some GI JUDO, Groundwork, And Wrestling. Which would be easier for me and better according to my past experiences with these combats. So should I go with the oldschool boxing or mauy thai? Any preference or it doesn't matter which one I learn (First).
