Same..... it was my first Persona / SMT game. It's a bit difficult mentally to make myself refer to the characters by their original names even though the PS1 names are mostly objectively dumb sounding. And the character sprites are harder to distinguish in this version, like the main character and Nate look pretty much the same from the back.
It's also slightly weird that Mark is apparently still called Mark most of the time in the original, though I knew about "Elly" and "Brown". I wonder what the deal is with many of the characters in Japanese Persona 1 and 2 having English nicknames, though I guess it made things easier for when the US branch decided to Americanize all the names.

I'd add "the intro movie" as the only other thing the PS1 version did better, in spite of its technologically primitive look.
At least the first half of Persona 2: IS (again only the original) gave us a good non-dated looking version of that
