How exactly would Luka have been better for Marinette?

It seems to be a common thought that Luka would've been a much better boyfriend to marinette that Adrien and I don't get why.

Marinette wasnt as into him as he was into her. Luka knew that. Which also leads to my question as to why he would pursue her knowing she was still in love with adrien.

The only think I can think of is her not being a mess around him.
