ProFX or SoundBlender; TDM or RTAS

[sidereal]

Looking for some killer way out special effects plug-ins and I'm trying to decide between the Waves Pro FX bundle or Wave Mechanics SoundBlender. In terms of cost (Waves bundle $1,000; SoundBlender $495), the SoundBlender seems more attractive, although the capabilities of the Waves bundle seems more broad.

Any thoughts on favorites? Anyone used both?

Also, what are you all doing about the TDM/RTAS thing? I see the Waves stuff is available either on TDM *or* RTAS and not both. What a drag. I'd like to be able to have the choice of using host power or DSP power. It would be better if the plugs were packaged in both formats. Or am I missing something?
