They got real ugly when I went door-to-door sharpening knives one summer. I charged double for serrated blades said:
What do you use for sharpening serrations? I use a Spyderco Tri Angle sharpmaker with decent results.
OTOH, my EDC is a SE Delica and I am very pleased the way it performs. (I also have a PE version, so I can make the difference). PE is easier to maintain indeed but SE lasts longer.
But since the question was mainly about the looks rather than functionality, I think that all depends on the design. Some knives look better with serrations, while to others those just don't fit. Also, there are several brands that developed their own style of serrations (for instance Spyderco and Cold Steel) and some of them may be more eye appealing than others.
And of course, as they say, beauty is in the eye of the beholder, so the subjective factor is very important here.
