My perspective on this might be a bit different, since after 20+ years of dabbling in electronic music (including graduate-school projects), a few years ago I realized that audio engineering is just about my least favorite thing to do with a computer. It has very little in common with playing music, which I'd much rather spend time on.
So, if you're in any way like me in that regard, here's my advice on Digital Audio Workstation (DAW) software, of which ProTools and LogicPro are notable examples:
1. Avoid the rabbit-hole altogether: recruit a friend who's really into audio technology to do the recording/engineering for you;
or
2. Download some product demos, and see which is easiest to use for you personally (compared to GarageBand), disregarding what anyone else says is the "best tool." The learning-curve on these DAW apps can be enormous, with no guarantee you'll like the tool any more after mastering it, than you did in your first week of messing with the demo version.
Note that any audio interface hardware you buy (I defer here to others' hardware recommendations) almost certainly comes bundled with a basic audio recorder/editor -- that might be good enough!
P.S. Having said all that, on those rare occasions I edit audio, nowadays Audacity is my go-to app (it's free and versatile). And you can't go wrong with AKG gear. But your mileage may vary...

Good luck,
Mick
