Which is better- hit debut or hit comeback? for a new group?

Hit comeback>

A hit comeback is way better a group with a hit debut puts so much pressure on the group, the company and the fans and the fall would be hard to take

Hit debut is a set up for flopping so hit comeback >>>>>>>>>>>>>>>>>>

Both

Hit cbs which are consistent

Take Twice as an example...their debut song wasn't as big but Cheer Up was one of the biggest comebacks in KPOP. It was CRAZY popular and really helped toward making Twice THAT group

Hit cb look at aespa, or Stayc. Even twice is the best example.

if it was either or then hit debut...

since there is the old addage that first impressions count...

and loyal fans are more easily gotten from the get go as oppose to over time...
