I've had mine since late 2001 (302 only). It was jumpy and tended to
overshoot early on but Marty Eiler at Caracole worked some magic with
the plumbing and it now matches my B-40 in response as well as
strength. The only problem has been with the gear warning system which
failed intermittently and finally gave up the ghost (yes, we checked
the switches and wiring all the way to the connections on the 302).
Next time the unit comes out for calibration, I'll send it back to have
this checked.

I use it with WinPilot Pro and am quite satisfied. The 302 is the only
system I've used, so I can't be of any help on comparisons with others.

I have used a 302, without the 303, but with Glide Nav for several
years:

1.Reliability. 2 cases of internal seal failure otherwise no problems
2. Wind calculation - not done in 302
3. Good TE compensation no problem with over-read on thermal entry. I
use 1.7 audio and 2.3 vario and see good correlation with B40 readings.
4. Reads lower sink than B40 in cruise but never ran the numbers to see
if difference matched polar. No problem finding thermals in cruise.
Not an issue.

I did replace the display as I had one with incorrect polarization.
Not a reliability issue but a poor parts screening process.
