As far as I know, there are no PvE servers with very good balance.
I've been checking populations regularly on my server (a US PvE server) as I have toons on both factions. Empire outnumbers Republic by >2:1 at any given time that I've checked the stats (doing /who via zones, levels, classes - for example, last night there were 47 level 50 Republic tons at 10:00 PM CST. There were over 200 level 50 Empire toons at the same time. Imperial Fleet had 230 players at that time. Republic Fleet had 84.
I've been checking these stats regularly for the past four weeks, and Republic numbers (or active players at least) seem to be dwindling compared to Empire. Granted, my info is only slightly better than anecdotal, but still, it's obvious that there's a huge faction population imbalance on my server.
From what I understand, basically from what I have read via those who have collected similar data, the RP servers offer the best in terms of population balance. So maybe look at a RP-PvP server.
You're just not going to find a regular PvP server with anything even remotely resembling faction population balance. Your only two options there are join the zerg or become mob gank bait.
