Interesting comparison.

However, about Volkslogger:

When flight log memory is full the unit stops logging rather than
wrapping around and erasing the oldest flights - not ideal.

I'm not so sure about the "not ideal".

First, you get warnings every few minutes if and when there is "only" 8
hours memory left (this can get on your nerves). This should be more
than sufficient for most flights. And it is possible to change the
logging interval in flight once the warnings begin.

Second, in a contest, if your memory gets full, it's better to have the
beginning of the flight remaining in the memory: you still might get
points up to the moment the memory is full; with the wrap around
system, your whole flight will be invalidated by having the take-off
and start deleted. Of course, this is only true if we are talking about
a single flight in the recorder. Unlikely to happen if you use a
sensible logging interval.

An important feature of Volkslogger is that you can easily use a 10
second or so interval, the logger will automatically change its
interval to 1 second for start line, finish line and turnpoint sector
passage. I don't know if all the other loggers do the same. Perhaps you
could include this in your comparison?
