Be aware that the NN1G Mk2 kit from Dan's is not the rig featured in the
recent (November?) QST. It's designed by the same guy, NN1G, and has some
common elements, but it's not the same as the 40-40 (the rig in QST). I've
built both the 40-40 and a 20M NN1G Mk 2. The 40-40 was easier to assemble,
is only one board, fewer parts, easier to put in a box (mounting the air
variable in the Mk 2 with a vernier drive takes some fiddling) and the
performance seems (in my limited experience) to be similar. The 40-40 is also
about $20 cheaper.

As for real performance differences (NN1G vs 40-40), can anyone offer any
info/opinions?

Also, what are the advantages, if any, of using a cap for the VFO instead of
a varicap? Or vice-versa? No flames intended, just wondering.
