I personally like to create a new branch locally - sometimes I'm experimenting and get ahead of my commits, and then I'll make 3-4 commits in bite-sized concepts. Other times I'll commit something that seems like it will probably work, and then I realize it doesn't, so I'm able to revert/reset the commit (so the commit is deleted rather than seeing a commit and then a revert in the log). And once I'm close to done, I can even rebase so my clean commits are all in a row. Then I push my branch.
I lose all that flexibility as soon as a team's process demands I push my branch as soon as I create it. I can no longer rebase (I still don't understand the guides that explain how to use rebase after pushing), reverts add noises to the log, merges from master interrupt the flow, etc. So in that sense, I can see the allure of a squash-and-merge to master.
I just don't think that pushing an empty feature branch takes advantage of the benefits of using git.
