I use the EHX MicroPOG, there is nothing else that tracks as well. I like the 3 octave range and polyphony but you are right in that the upper octave is a bit synthy. I find that one has to work with the levels and blend to tame it but it will never be perfect. Still, I don't think that there is anything else like it on the market except the big POG and HOG.
As for chorus, I used the Danelectro 18v Cool Cat for years and still think it is a great pedal, especially for the price. However, I finally aquired a Fulltone ChoralFlange and that will be my chorus from here on. I was going to get the Analogman Bi-Chorus w/ Deep switch until I found the Fulltone. Who knows, one day I might get the Bi-chorus anyway

, the Analogman chrouses are really great pedals.
Two other Choruses you might check out are the Tech21 Boost Chorus and the Source Audio Orbital Modulator. The Boost Chorus seems capable of a wide range of chorus sounds and there are very favorable reviews on the pedal. The SourceAudio stuff is very good and I am having serious GAS for their line of pedals, especially now that they have released the Midi Hub.
The Ola by Strymon looks really good too, but I have only seen/heard the online demos.
Good luck!
