Personally, I love romance, so I'll read a lot of stuff if it has any sort of romantic subplot, even if that's not what it's about. (Of course I end up enjoying it for other things in addition to or apart form the romance). Hell, I'm actually reading Koisome Momiji as I type. Yet, I feel as if Weekly Shonen Jump always produces the same type of romcoms, personally, complete with similar character archetypes, settings, and especially tropes, with a few twists here and there. For comparison, Weekly Young Jump has Kaguya-sama: Love is War, The 100 Girlfriends Who Really, Really, Really, Really, Really Love You, and Kowloon Generic Romance all being serialized right now, and all three of them are quite different. I guess the magazine's strict like that - stick to what works for you (even though GoToubun is outselling WNL by a country mile).
Miitama and (hopefully) Guardian. I honestly can'tsay for the bottom 5. But damn, we now have at least 3 gag manga in the magazine. One of them has got to survive.
