Talking about version control systems can be like talking about religion or 
politics. People tend to have opinions, strong opinions, and their experience 
tends to center around systems they've used extensively, mixed with heresay 
about products they haven't used.

I think you owe it to yourself to give a few of the top tools a try - even if 
it's just a matter of checking out source from public repositories to build a 
project. Preferably, though, a thorough test of versioning a website and 
stepping through what a likely workflow would look like with the various tools.

I feel that everyone should have experience with a traditionally centralized 
version control system and with a distributed system - so that they can be 
familiar with the strengths and drawbacks of each and, yes, develop an opinion 
on where they would gravitate toward one over the other in future situations as 
they arrive. The systems I'd recommend looking at have already been mentioned:

Centralized:
- Subversion
- Perforce
Distributed:
- Git
- Mercurial

Personally, my preferences are Perforce and Mercurial. But I recommend playing 
around with the systems and getting a sense for how they store versioned files, 
where state is maintained. Whether, for instance, perforce's default of locking 
files that aren't marked for editing stands more or less in the way than all 
the dot-directories that subversion scatters through your working directories. 
Whether the subversion/perforce approach of using paths to separate branches 
(as you might separate versions on a file server) is harder to keep straight 
than the distributed approach that git and mercurial take. And, though it's 
likely you'll be leveraging commandline tools for much of the work, do a survey 
of the graphical tools - including, of course, the BBEdit integration - for 
working with the repository, merging files together and resolving conflicts 
between revisions. It's also worth taking a look at github and bitbucket to see 
what they offer.

Re: Get a list of files found in a folder differences call

[Charles Albrecht]

You can use the diff(1) or rsync(1) comnandline tools to get this info  
out.

(with diff -r, you just keep the lines that start with "diff -r" or  
"Only in". With rsync, you use "-n" to see what it would copy.)

I don't know that you can get a list out of bbdiff, FileMerge  
(opendiff) or p4merge.

Perforce will prefer P4EDITOR, but if EDITOR is set, it will use that.  
I set them to:

P4EDITOR="/usr/bin/bbedit --wait --resume --"

And similarly with

P4DIFF="/usr/bin/bbdiff --"
P4MERGE="/Applications/p4merge.app/Contents/MacOS/p4merge"
