Git was an improvement over SVN in some aspects, but a monumental regression in others. There are no two ways around that.
Mercurial is better than git in a bunch of ways. It is much more usable because it has way fewer footguns. But it has some of the same shortcomings as git when compared to SVN. I won't call it perfect.
The reason we didn't get svnhub is that some git fanboy nabbed the domain and essentially said "you shall not have it". Joking aside, there was Sourceforge with working SVN support. But I would say that Sourceforge lost market share for a lot of reasons, not all of them technical. Wrapping Windows downloads in adware installers was only one of those many crazy unforced errors.
Am I bitter? Maybe, because I have to use tools that could be so much better. I've experienced better and every time I am forced back to git, it feels a bit painful because I know what we could have instead. If am bitter, it is because of my experience with a wide range of tools.
