何といっても + [sentence]
[topic phrase] + 何といっても + [sentence]
何といっても (なんといっても) is an adverbial expression meaning "no matter what anyone says," "after all," "without a doubt," or "by any account." It is used to emphasize that something is the most important, best, or most notable point about a topic – regardless of other factors or opinions that might exist.
The phrase literally means "even if you say anything" (何と + 言っても), but it functions idiomatically to highlight a standout quality or undeniable truth.
何といっても is used to single out one thing as the most significant among several possibilities.
It can also be used to state something that remains true regardless of what else might be said.
