I've had no experience with either of those pedals you mentioned, but if you haven't yet considered it you should really check out the Earthbound Audio Supercollider as it sounds very similar to the Tonebender. For reference:
They are mkII germanium tonbender clones rather than clones of the current silicon 3 knob version. Thought id mention that in case you have heard the current issue and are looking for a clone of it.
