As a fan of Midtown from before their debut LP album, I have to say that Midtown has a better sound than Sugarcult. Sugarcult is a band I have just recently (past year and a half) gotten somewhat interested in, although I don't love them. But Sugarcult doesnt sound like midtown, they are more of a poppy sound, as you mentioned. They are addicting, but they sound too much like some other poppypunk bands who I also like but can't listen to for too long (New Found Glory, Allister, etc.) Sugarcult is very straightforward in trying to get you addicted to their music, showing flashes of excitement and fun but Midtown is much more addicting for me because I can listen to them and never get bored. They're not so sporadic...its hard to explain.
