I read a white paper on BDM and that seems like a no brainer

The ability to step through code on the board seems invaluable.
Here's what support told me:
"The 13192DSK is based on the first generation chipset that has the GT60
and 13192 RFIC (two chip solution).
The 1321xDSK is the 2nd generation where be combined both devices into a
single packaged and integrated the TX/RX switch which lowers the
component count and cost. Functionally they are identical, but the
1321xDSK is based on the 13213 SiP and will be a less expensive
solution.
Both kits have similar functionality, same amount of memory etc. The
1321x has a little nicer packaging in that the dev boards come in a
plastic case.
The Maxstream solution is based on their module that uses the first
generation two-chip solution. Functionally, it is the same as the
MC1321x solution."
Now to decide whether or not to go with a smaller outfit. I don't know how the way MaxStream has put the components together could affect operatoin.
