TOR is pretty easy, idk why but i previously had trouble with I2P. I'll probably get it working to view websites this time, though as for self-hosting, currently undoable due to a lack of a way to do it (tho if i figure it out and it wouldnt just randomly disconnect, i'll host it on my laptop right here).
I plan to one day get I2P and TOR up. I2P is probably less-fedfilled for now, but TOR is far more used so it will be on both.
I did not think of it that way XD. Tho now that I think about it, that makes a whole lot more sense.
