I find hg much more pleasant to use than git, and can generally still work in git based teams while using hg.
I find pijul's approach much more interesting than git's, and look forward to pijul (and others :) pushing forward how we do revision control.
I don't believe git to be the end of the evolution of revision control systems (which for me has looked like cp -> rcs -> cvs -> svn -> git|hg), and find git lacking enough that I look forward to what the next generation does.
Would I argue that you personally should branch outside of your git centric world? Of course not! Just as I've worked with many devs who live their lives gainfully employed only knowing Java, or sys admins who only know Microsoft, it is up to you as to if you wish to explore different approaches and styles to achieve your end goal.
