Can there be two?

I would expect any TT user concerned about performance to be
using
cached templates and the XS stash.

Without XS, TT in

Sounds like it could be great for people who are stuck using
CGI.  TT
doesn't perform well without the cache.

That's good.  Some of those (tables, date formatting) are
practically
part of the language at this point for me.

I think most people are concerned about performance - even
if it is a second 
thought.  I think there are plenty of people who don't have
a choice about
how the server they're using is configured.

I do agree though that those who are really really concerned
about the 
performance have tuned their code to the nth level.

Yup.

Bare TT does OK.  Stash XS and cached templates just do
better.  
CGI::Ex::Template just is a step towards making them not be
as necessary.

Of course I don't think there is anything keeping somebody
from writing the 
get_variable and set_variable routines of CGI::Ex::Template
in xs.  That 
would be interesting.
