Variety versus specifity

A question that I wondered about a lot on my last month excursion and which I've found myself wondering about again on this one, is which has more value, speed or specifity?

Is it better to hit a million places and taste a little of each, or to hit a few places and really indulge in each.

A million flavours? A few good meals?

So far I've mimiced my previous travel experience, by heading up North super fast, stopping at a few places, taking lots of long bus and train trips and marvelling at the landscapes. This would surprise everyone I travelled with last time, because I always wanted to move slower, and try and understand each place a little more just by slowly walking thorugh it day by day and drinking coffee at random places and seeing how it lived, instead of seeing it's sights. But that's how I've started this trip.

But now I'm in Bangkok and about to go South. And I think the South will be slow and easy and I'll probably only go to a few places and spend time in each one. Maybe I'll be qualified to answer that question after this trip. But I probably won't be. Maybe there isn't an answer. Certainly they both have value.
