yeah TC Works (if that's who you are referring to) doesn't exist anymore as far as I know. I have the TC native bundle that I bought years ago and I actually still use the EQ and Reverb ... I would put them in about the same class as Waves, maybe a notch below. They are very easy on your CPU which is always a plus.
I remember when I first heard of TC Electronic 10 years or so ago and I had thought they were the same company ............
EDIT: ok I stand corrected ... either they are the same company or they were acquired by TC Electronics ... and they still make plug-in's
