Few Macs will keep up with the PC I custom built for Adobe Premiere Pro.
IF you should decide to get an Apple computer I would have a look on Final Cut Pro X as well. I have a 8 core dual GTX 980TI 64GB RAM video editing machine myself with Premiere Pro - it's about as fast as my Macbook running Final Cut Pro... Adobe's video engine really sucks. Final Cut is flying (6 4K streams without pre-rendering ... no problem) on my OSX installation (google Hackintosh) on the video edit PC
On Topic: I have Logic Pro and Studio One... hardly ever use Logic - I think Studio One is way more intuitive. Give it a try
