Per my previous post, I prefer the FA-VA5 as well ... and it is about
half the cost of the Rig Expert.
One of it's nice features is the 5-band SWR display for checking which
coax lines go to which antenna. I obviously don't have to use that very
often, but when I'm changing things around it can be pretty handy.

For field use, if you can get by operating a fairly complicated instrument with
just three buttons, the latter is the best of the bunch IMHO.
1) It is very portable2) It can be OSL calibrated over its full frequency range
one time (similar to a master cal in the DG8SAQ)3) It displays SWR, Smith Chart and
tabular values.
4) Multiple measurements can be saved and imported via USB to the VMWA
software, which is amazing.
5) It can be a "test head" operated with the VNWA software.6) And not least,
you can read the display in sunlight, although this is a time when I need my bifocals.
