I have worked with both MKS's ksh and the Aspen Korn Shell.
I prefer the latter. the MKS korn shell is their own implementation
of the Korn Shell ; the Aspen is based on AT&T sources.

The MKS ksh is full of bugs. Lots of shell scripts in /bin and /usr/bin
fail with this product. MKS ksh cannot handle filenames of exactly
14 characters long, it thinks all filenames in directories are
null-terminated. I suspect they ported their DOS ksh to *nix
instead of the other way round.

I did not even bother to look for other bugs.

The Aspen Korn Shell works just fine for me.
It only displays a copyright message if it is invoked with -ksh
(ie login shell).

Note that you still need ksh source for job control, 
because currently these ksh's are not compiled with 
job control enabled.

Disclaimer: this is just my opinion.
