Like he said, it depends. If your first remote as RP is a sundew, you can count on the runner to come and trash it. So no, unprotected sundews early in the game are (usually) not that great(still a -2 in your favor!)
NEH just spams a(1) asset every 1-2 turns, and if they really want to trash the first 2 marked accounts, fine, you know you will find some PADs later.
Depends on your ID, Deck, Playstyle, do what works for you! If you find no one will run a single server if you drop 3 assets in one turn, what's your point in stopping to do so?
