Note that XAPP477 PicoBlaze/MicroBlaze comparison has now been removed from the website.
This information is now included here:

Section II - Embedding Processing and Control Solutions
Here is a non-technical (and obviously unofficial) summary I've used before:
PicoBlaze or MicroBlaze can both be attractive solutions but they differ in a number of important details.
PicoBlaze is the girl next door. I can get a date within 5 minutes, wear jeans, and have a good time. But nobody else is impressed.
MicroBlaze is the prom queen. I have to be smoother in how I ask her out, need to get a haircut, wash the car, and I'm not getting out of the restaurant for less than $100. People call me the next day for details.
Don't ask about the PPC405 or 440 - My analogies break down there.
