Maybe it's just me, but I tend to think that maps like this are slightly underrated. Probably not by much or at all if I actually think about it, since there'd be more pp if those sliders were actual bursts/streams like in the harder versions, but it sure feels like it.

Osu! also has different rankings you can shoot for, with SS being the best (Hit every note and have 100% accuracy). There are also mods like Hard Rock, Hidden, Flashlight, and Double Time/Nightcore if you want to increase the difficulty even more.
