In my mind Git solves a different problem that Linus Torvalds was facing: many people working in parallel with only some of the ideas pushed upstream, but many people wanting to make changes and easily being able to move forward to the latest changes from upstream.
My extremely opinionated view is that most people should use Subversion unless they have a very complicated team structure. And that means every solo dev working by themselves should not complicate their own lives by using Git unless they are really comfortable with it already.
Why would a solo dev choose to use a client-server version control instead of one that works fully locally?
You can ask Subversion to create a repository anywhere you like in the filesystem.
As a former member of Meta's source control team, I believe this with pretty high confidence -- many of the workflows that we rolled out within Mercurial/Sapling, and caused it to consistently be the most loved developer tool at Meta for many years based on surveys and interviews, have been adopted and improved by Jujutsu. See my testimonial, the first one at [2].

(Disclosure: I'm obviously biased towards the Jujutsu workflows, and its creator and I worked together on Mercurial. But I like to think that this specific belief of mine is pretty data-driven, both via stated and revealed preference.)
Atlassian Sourcetree in theory works with Hg (because Atlassian's Bitbucket used Mercurial as their primary version control system before moving to git) but SourceTree is Windows/Mac only, there is no Linux version for some strange reason.
Trying to run SourceTree on Linux via WINE fails because Sourcetree can't be installed with the 'Administrator' user and recent WINE releases have (accidentally?) removed the ability to run a WINE program as a non-Administrator user.
I haven't personally tried (yet) to install Sourcetree on a Windows machine and copy the directory over and try via WINE, but it's on my list to do.
I haven't used it myself but I might for a solo project I'm involved in right now.
A good read (not my article, linked from the Fossil site):
Pretty much what is listed in the OP cheat sheet.
