svn is simple for simple things - but those things are simple on
bzr/hg/git whatever too. Cloning, diffing, committing; those are the
same on every tool. More advanced things are really a PITA in svn - svn
is actually extremely counterintuitive IMHO. I mean, what's intuitive
about using copy to create a tag, really ? 50 % of the time I create a
branch for numpy, I screw up because I need like 10 commands, which fail
half of the time for stupid errors or time out. It is really a drag to
handle branches in svn, specially when it takes 10 minutes to merge 5
revisions (granted, this is at least partially due to the server hanging
You're right that there is no decent GUI for git - tortoiseSVN has seen
years of development, so obviously, all the other tools are far behind.
And from a GUI POV, I think there are some deep, unsolved problems on
how to present things simply. I don't think anybody has found a solution

Really, the basic commands are the same for all the tools out there:
But I am not denying that git has some rough edges UI-wise. In
particular, handling of remotes (forwarding changes to other
repositories) is still too complicated for simple tasks, and some error
messages are cryptic. But so is the case for svn, really.

I agree that tools cannot solve the problem of lack of test. But to give
you a scenario: I had a couple of hours to spend on triaging bugs on
numpy for 1.3 release last WE. I have done almost nothing: I can't
easily get tickets with attached patches, I can't control the bug
tracker from the command line (I can't say: give me all the tickets
since 1.2 with attached patches, give me all tickets on numpy.core since
1.2, etc...). I find the whole workflow extremely frustrating personally.
