BCH only advantage is lower fees and quicker tx times. That is a temprorary advantage, because its caused by nodody actually using the chain in combination with bigger blocks.

Bigger block has many disadvantages, including more centralization, less full nodes, etc.

BCH is also controlled by a small group of people.

When (if) people actually start using BCH, the block will eventually fill and fess go up, confirmations will take longer. At that point, with almost no devs working on BCH, only answer they have is to make blocks even bigger. As block grows, centralization increases even more. When the block are about 1GB, even those big blockers will realize that it might not be that great idea.

At short term, BCH may be better option, but for long term, i would bet on people who can see and plan long time ahead, have development power, etc.
