I tried them a bit, and frankly some nodes are really bad for egg hunting since they put the Maha Naga in the second part of the fight instead of the last. Only the central node (city one) is the good one, as they put it at the end, but you pretty much need a Berserker or Saber to kill it, it's 175K HP after all (unless you get a crit, but then you're leaving it all to card RNG). Other nodes are just bad simply because they only spawn two enemies instead of three, screwing with some farming teams.
Honestly, it's to the point I recommend to only bother with the city node, but you have to bring a ST Saber in there with its NP ready to be used. The one with only arrows is also fine too, but be careful as it has only Berserkers. The rest are really bad.
