What you find compelling or appealing to your feelings is totally and absolutely irrelevant. You can only have one master.
This is actually an aspect of modernism that many of our Popes have spoken so heavily against.
It doesn't matter what you want, all that matters is what God wants.
If you do something for "aesthetic" reasons you are literally putting your sensual pleasures above God.
Some masses are unpleasent in some ways, but regardless Christ is there as well as a chorus of angels.
If you have any suffering, offer it to Christ as a sacrifice for other souls or your own.
It's not only wrong but it's putting you in a place where your ultimate judgement of things is your sensual feelings and passions, which leaves you totally open and vulnerable from outside negative spiritual influences whether just through social/cultural/psychological manipulation or outright spiritual attacks.
All the problems you have with the NO mass (comes from priests, not in the actual rubric of the mass) are because of the same error you are commiting. People change things to be more appealing to people. They think they will like this music more, or prefer certain things one way or the other. The problem is focusing on what humans want instead of what God wants.
God has a Church, a parish near you, and is giving himself to you physically there. What matters is that you humble yourself and accept his gift to you, not that you look for how you can have the most enjoyable aesthetic experience or feel good.
Also for what you actually said, the Orthodox are in error and reject the Pope and actual hierarchy of the Church, they are outside the normal plan of salvation and we can't be sure they won't all be damned. (God will likely/hopefully extend his mercy to them though we can't know this.)
Schism is a mortal sin and can damn you (of course knowledge can effect your responsibility of this, but by the fact you are here you likely know enough to be responsible for it).
