I would not call any of these concepts superior to the other. Different
people just prefer different things.

I've read about the push/pop feature, but I'm more the "throw away the
old stuff and start over" kind of guy. I'll never need to pop. :-)

wrote about ? My goal is to really start over, having nothing left from
the previous history.
