Opinions on the tsundere trope?

Personally “Hell yeah, good shit”

But I noticed the tag of “tsundere” isn’t that popular, it’s more used for older series

Is the term still relevant? Do you like the trope? Also what in your opinion makes a good tsunderr? Or what character is your favorite tsundere?

Also is this question an opening to discussion or just me disguising my search for good reccs, or both? You’ll never know
