You'll have to do the maintenance either way, and a belt is typically easier. I suppose the one advantage a chain design has is the absence of camshaft oil seals.
On occasion I've been able to do a chain job preventatively. It's hard to catch though, because it's not as easy as just peeking behind a plastic cover to look at the condition of a belt. :/ It's also not a 'recommended' maintenance, nor is it something the ordinary motorist (or indeed, mechanic) would even consider to be a maintenance item.

Thats my "case" for timing belts, at least for OHC applications. as for front wheel drive, that's why I'm in a Miata right now. the timing belt shouldn't be too hard on that one, it was replaced at 80k, and isn't due until 160K.......unless the water pump craps out.
