Touchdesigner and processing

Hi! I have been using processing (processing.org) for many years and recently started to discover touchdesigner. Before processing Ive been using the jitter part in Max/Msp.

How do you consider touchdesign towards processing? Speed etc? Sometimes I felt that processing is a little bit slow for live visuals. To make it really smooth I need to export it as video but then I am loosing some of the interactive parts.

How do you consider touchdesigner in this perspective?
