Heck, if you like it then that's all that matters. I don't say that to be snarky. If you like your mix and the decisions you made then you stand by them. (just do so in a good way, which you have, but sometimes people get too defensive it seems.)
I've come to learn that guitars tend to be sacred animal to some people. Usually guitarists. So I approach guitar sounds as "whelp, that's what they wanted, for some reason. ( See
https://tinyurl.com/y45dma4b (long read but the gist comes across quickly)). So I tend to try not to do too much to them because someone probably fought for 'their tone!' early on. That's not to say you can't or shouldn't do too much to guitars but I tend to leave them alone and maybe add some high end and cut some subs. But one can view guitar tones forensically as sonic DNA as to what the band wants to sound like. But if it sucks fix it. I know that doesn't help right now but I wanted to say it anyway. I do think the added distortion feels "fake" and kinda throws off the ear. Mine at least. Maybe both. But definitely one.
I honestly didn't notice the panning of the speaking. A totally valid way for highlighting things though. On re-listen, I'd consider panning the vocals back center after the speaking, when he goes back to his singing voice.
I am unfamiliar with the "Does this sound like Sh.. test". As one could tel from my own drum sounds. Wait, it's been a while does Black Hole Sun not pass that test? I though they sounded cool but it's been a while... (Also, related, this was kinda cool on some level but I did hope for more insight.

I never really used the TG1...5 but they certainly seem capable to get that to happen. But maybe the just didn't in this instance. Or if they did then maybe the issue is before the plug in. Just being Socratic.
It's certainly a passable mix. It does sound like a "guitar and vocal mix" I just kinda wish there were more to latch onto of the other elements. It's pretty good. Could be better. None of this is a put down or anything like that.
Am I being helpful or just weird and annoying? Or both? Which I'm ok with as long as helpful is in there somewhere. I loathe talking about Hz and Dbs normally and tend to be obtuse.
It doesn't have to sound good. People just need to think it sounds good.
