I totally agree. Microtonic brings it to a whole other level. I was wary of needing to pay $99 bucks more, but OMG it is worth every penny.
I’m definitely getting the PO33 and PO35 as well. The PO35 also has one instance of Microtonic in it from what I understand. That means if you have the PO32 and PO35, you can have three Microtonic kits to jam on (actually six if you cleverly use the morph function).
