Depends on two things IMHO: (A) how important the commit is and (B) how many lines of code are changed. Squash makes sense usually when you have have a branch with multiple small commits that affect the same thing. Doesn't make sense to squash 2 commits affecting large parts of the application just because your commit has to be squashed before merging.
