Nah, you got the right section for posting.
Here's an excerpt from a book about guitars. It describes it pretty well.
"Fret size has a great deal to do with the feel of a guitar. Low frets allow the player to feel the fingerboard, but leave little room to add vibrato by pushing the strings downward, or to really grip them for bending. Tall frets are the opposite (they can be gripped and bent by pushing, but it is more difficult to play normal notes due to the height from the fingerboard).
The width of the fret determines the amount of wear that can be expected before 'fret dressing' is necessary. Narrow frets wear faster but stay more in tune as they do, while wider frets last longer but sharpen in intonation slightly as they wear."
So there oyu have it. I personally prefer the lower frets, because it's so much easier to play chords and different notes, and you can still bend the notes by pulling down across the fretboard. High frets irritate me a bit.
I'm not sure, but guessing off general physics, sustain would last longer with lower frets. And I know for a fact that low frets are better for articulation.
