S12 XGATE Debugging

Hi all,
 
I am trying to choose a processor for my next project. My previouse project used a S12 device, and worked very well, the only problem I had towards the end was a bit of a squeeze on RAM resources. A good code trim seemed to sort it out!!
 
So I am thinking of going towards an S12XE device for my new project - they seem cheaper (I guess Freescale want to puch their new devices) and I am thinking that some of my driver code could be re-used, or at least retain the same style. As a bonus, I can also re-use the Metrowerks license I have!!
 
Debugging on the particular S12 device we chose previously was quite bad - the silicon had a bug that meant the trace facility in Metrowerks would not function, and only 2 breakpoints - felt like the 1980's...
 
So, my question is - is the debugging on the S12X devices any better?
Especially with the trace support - is this a useful feature - I'm thinking that with the additional XGATE accelaration there's a good chance the Trace module can get confused, or that debugging without Trace is a nightmare?
 
Any experiences, general gut feelings, recommendations gratefully received.
 
Thanks,
Mike
