HAH, beautiful. Faving this. I once tried to do a similar high resolution icon or rather a logo for my band. I wanted a cat chewing on a jack cable. (Because the band is called 'The Cat Ate The Wires' It didn't come anything. Looked more like a hamster xD .
It's been a few years, but when I was in high school I did a co-op semester at print shop/graphic design place. I had to use AI for a couple of things and while it was definitely faster than Inkscape in terms of rendering & UI response, I found the tools and workflow much more convoluted. Usually after a few days of using a program I can get used to all the main functions but not with Illustrator - I think I ended up working with Inkscape and then just tweaking it in AI for printing.
But like I said that was years ago and I didn't compare the two in-depth. A lot has probably changed since then.
