Who is the more irritating love interest?

Neither. I chose Lana though, because she did do harsh things, even if it was after Clark had jerked her around for years. Laurel's biggest "crime", that she was bashed for, like that, was daring to be angry at people who'd hurt her, in one form or another, and going after/distrusting a murderer.

Lana is a million times more irritating. And her sendoff was “she goes on (offscreen) to be possibly a better hero than even Superman!” Even if Laurel annoyed people you can agree that her send off (the real one not the Earth-2 one) was BRUTAL and undeserved.
