reiser4 Vs reiserfs for / on new Gentoo isntallation
 

I know that some of you have been using reiser4 for some years now.
How does it compare in performance and reliability in terms to
reiserfs and xfs?

A few years ago I remember there were problems compiling or running
some applications/libraries on reiser4 - are these problems now over?
Any gotchas?
