I kind of want to get a little more context for the comparison:
These are all pretty low power cards. I've never found spider spawning to be very impressive, even within the context of a lower power graveyard format, with some power spikes: and it was those power spikes that mostly contributed to it being unimpressive. It (and worm harvest) could be anecdotally impressive, but they were never consistent. I would expect reach of branches to be similar.
I don't think its unreasonable to have a level 0 analysis of whether these are even the droids you are looking for.
