I'm in the same boat (having used UnitTest++ for years) and I wonder the same, though I do see some points already: - adding a custom main() to unittest++ was pretty messy - unittest++ is not single-header, meaning you have to recompile all flavours everytime you switch toolsets - that nested sections stuff looks good and readable, so even though it might be doable with unittest++, this really attracts me more That being said, I would like to hear from the author or anyone else who can compare them. But likely I'm going to use this for the next project just to check it out.
