I currently attend a NO mass, no TLM anywhere near me. I'm very fortunate, in that my priest is very holy, and we have Latin, only altar boys, incense, organ, sacred music, etc. When I compare my current NO congregation and fellow Catholics with my previous TLM congregation, there's really very little difference. Faithful practicing Catholics are faithful practicing Catholics, no matter the mass.
However, we often visit family in an area where the NO is excruciating. I've attended Holy Hour at that church before, and know that there are a lot of very faithful and traditional Catholics there (again, no TLM anywhere close), but the personality of the priest overwhelms the congregation and sets the whole tone for the parish. In that kind of environment it's inevitable that the loonies and dissidents are front and center. Consequently, I've learned not to lump everyone together based on my overall impression of the congregation; I've learned that the orthodoxy (and good taste) of the priest makes a huge difference.
