6.1 -release syspatched or -stable

Hi

I am not a dev, just a user, so I use -release and -stable.

On amd64/i386 a fresh installed 6.1-release can be patched by syspatch
or with -stable is patched by compiling kernel and userland as mentioned
in FAQ (CVS and so on). Currently I use both ways on separate servers.

For 6.1 amd64/i386 is there a difference between a syspatched -release
and a compiled -stable (in base syspatched -release eq compiled
-stable)?
And what about the userland in -release in contrary to a fresh compiled
userland for -stable? For amd64/i386 I just want to understand the
difference if there is any to decide which way will be more suitable for
my new installations.

Many thanks. Oliver
