My take on this issue is, own equal amounts of each. The issue that caused the divide is the Israel v. Palestine of the Blockchain world. What do I mean by equal amounts of each?
If you hold 0.1 BTC, then you should also hold 0.1 BCH. The dollar values can fluctuate wildly depending on what reality decides with regards to the Bitcoin debate, and you can rest a bit easier as you HODL under your blankie.
