Thank you for the good question!

A little while back (a few months), I made this spreadsheet which  
compares the M4 dev boards:
https://docs.google.com/spreadsheet/ccc?key=0Am7wuPBwl_tbdGtXR1hpMzRCNzJpVWNYTE5hanowb0E#gid=0

One takeaway is that the TI and Kinetis versions of the chips had  
lower maximum clock speeds than the ST versions.

Also the TI versions seem to be non-stock at DigiKey.  Not the end of  
the world, but a little harder to obtain.

Also, it looks like Maple Native II is still vaporware... fingers crossed.

Also, NXP has the LPC43xx series which can clock to 208 MHz(!) and  
seems to have dual-core(!), but I can't tell if it has the  
floating-point unit inside.

My current favorite dev board is the FEZ Cerb40, but it shamefully  
doesn't breakout 4 of the analog signals.  I've started designing my  
own similar PCB that includes all analog inputs broken out...   but  
I'm having too much fun making music with the Cerb40 in the meantime :)

If anyone has any updates or corrections to my spreadsheet, please let  
me know, I'd be happy to keep it current.  The stm32f4 is imho the  
best thing to come along in a long time!
