DaMoshe
I get your point in a sense.
Meaning if someone is being Machmir due to superiority or the like, then yes they are not better, in fact thet would be in the realm of “Ba’lei Gaivoh”.
However someone who is genuinely Machmir due to a higher level of learning or because they wish to be more makpid on kashrus.
Well.
Yes that person is better then me.
They are on a higher level.
And that’s not my opinion. It’s explained in great detail by Mesilas Yeshorim.
