Just to clarify your post before: I delete and re-synch one of my machines 2 days ago, it took me almost 2 days to synch, but I was on the longer chain. The other computer running for the whole time (of that synching) is also on that longer chain. So if you re-synch now you can still get on this longer chain.
Similarly, the machine I deleted the blockchain on and resync'd from zero (only OP addnode IP addresses in conf file) looks to be on the longer chain. Not 100% certain yet, but from the looks of it, yeah - longer chain right now.
