I don't think you understand the meaning of "merge conflict", then. A
merge conflict is when you cannot simply merge the changes. If the
changes are on separate files, neither git nor hg will find this to be
a conflict, and the merge will happen automatically. Alternatively,
you can rebase rather than merging (git's term; Mercurial has a
similar concept for saying "put my private changes on top of the
history", but I can't remember the name), which again will succeed
automatically if the changes are to different files. Even better, the
merge/rebase will generally succeed even if the changes are to the
same file, as long as they're to different parts of it.

Play to a tool's strengths rather than its weaknesses, and you'll find
life a lot less frustrating. I'm fairly sure you could use the same
workflow with git as you were accustomed to with Teamware, only with a
few different names for things. And most likely Mercurial too, but
again, there'll be different names. Maybe you'll use branches for what
you used to use forks for, or maybe you'll have multiple clones of the
same repository, or maybe some other arrangement. Get to know some of
the myriad ways you can use modern source control systems, and find a
workflow that suits you.
