Back to what everyone stated, if it works, it works. And we leave it at that.
Vocals being buried, well lots of things can bury the vocals, like not mixing correctly. Once thing I have learned is, I don't have to record so hot like they did in the analog days. Lots of reasons they did that, but today, you don't have to. Once recorded, new people think it is too low. Once again, because they don't understand how to get the total volume up.
The main reason most say to record vocals and guitar separate, if you can't get both perfect in the same take, then it becomes more difficult to get a good recording. Once you have the bleed, doing a retake over a track with vocals and guitar is really difficult. But if you are really good at both singing and playing, then you are golden.
Me, I am not good enough with either to get a single perfect take in one shot with guitar and vocals. I compose a song, can't remember the words, phrasing, then trying to play as well. Too much going on for me. I do sing when playing to myself when getting the guitar tracked, then come in and lay vocals. It took many months before I could get comfortable playing separate from singing, but eventually I got there.
Your method is not bad, just a PITA if you need to do any edits, re-tracks, etc. cause, you are going to get bleed, that is the short and long of it.
As you move forward in recording, you may find what is hard now, easier on you in the recording process in the future. Just keep that in mind for future reference.
Just remember, most of us are doing the same thing you are doing, so we are just trying to help you with the learning curve. That's why we are here.
