The worst mistake I could have possibly made with Linux...

So I chose to install Ubuntu and Ubuntu studio on top (which as I understand is just adding a bunch of apps and maybe doing some configuring). I am a musician and visual creative. I'd like to know why I made the wrong choice in distro. Hit me with it!

Why is your distro of choice better than the one I picked at random for myself?

What bottleneck am I to expect due to my non archyness?
