I prefer bare bottom for the main reasons others have stated -- but for sure they still take effort: nothing looks worse than a bare bare bottom with waste or left over fish food swirling around the bottom of the tank.
So to keep your tank looking nice you have to remove it, either automatically with filtration (and then be prepared to change/clean your filter floss/foam often) or take the time to siphon out the waste on a daily basis (which I do religiously because a) I'm borderline OCD about tank cleanliness and b) I don't have a sump like pacu mom or esoxluciusesoxlucius).
I do have a tile bottom on my 375, and certainly looks better than bare glass, but as Rocksor mentions it's inevitable you'll get some waste/detritus build up in cracks, corners etc. -- I can really only recommend tiles for lightly stocked tanks (I only have 2 younger fish in that 375 so not a big deal, nitrates stay pretty low).
