NW Digital's DRAWS HAT boards is just a dual-channel soundcard with some
PTT circuitry and a GPS. There isn't anything really magical there
beyond very nice integration on one PCB for people who don't want to
cobble something together themselves. It also offers a good set of
documentation and potentially offers more than just community support to
get you going.
Your question probably should be more like:
Is anyone using a souncard TNC like Direwolf, Tom Sailer's
Soundmodem, etc. with Xastir vs TNC-Pi
I'm using Direwolf on an Rpi with a Syba USB sound device and it works
very well. It's TNC is generally able to dig out packet decodes that
most PIC-based TNCs (like the TNC-X, TNC-Pi, etc) cannot. The new
TNC-Pi9k6 could be a different animal as it has a lot more CPU power but
I haven't heard of any real decode comparisons yet.
The older Direwolf documentation used to have a comprehensive comparison
table against other TNCs in the "10.1 WA8LMF TNC Test CD" section but
newer versions dropped it. Here is an example of it from the Direwolf
1.3 docs. Overall, Direwolf's decode performance has only gotten BETTER
since then:

experience? Good, bad, indifferent? Compared to other modems like the
TNC-Pi?
