It's been said before. I'll say it again. Betamax vs. VHS

That said, even as BCH is a better alternative to BTC, it's not the end or the solution. This may be what's holding it back. There is no immediate need to switch from BTC. Even during the recent market freefall, BTC held its own with a drop less than 20% while alt coins dropped over 30% making it a prime time to purchase altcoins destined for a bounce. Then repurchase your BTC again because after the market retreat, it still hasn't really come back. It just reinforced people's sentiments about BTC.

I look at BCH as a stopgap. The real solution to BTC is a segwit2x, but who knows if we'll ever see that since the faceplant it made in November.
