I used to use cvs, subversion and perforce. After switching to git, it feels a lot more powerful, at the cost of more things that can go wrong.
My workflow with subversion was:
- regular update: update, check/fix conflicts, continue work
- commit: update, pick files I want to commit with TortoiseSVN, verify the changes in the diff view, write log message, commit, continue work
On GIT:
- regular update: stash my changes, change to master branch, pull, check for errors or dirty files (mostly endian problems), switch to work branch, rebase from master, check for errors or dirty files, unstash my changes, check for errors or dirty files, continue work
- commit: update, stage the files I want to commit, commit them, verify the changes, push
At several stages some obscure thing could go wrong that I needed to look up in the manual or on the internet, or needed to ask someone who used it for longer. That doesn't mean I think GIT is bad, I just feel it takes more time to be fully productive with compared to older systems. And I miss a few minor things from svn, like keyword expansion or properties.
