I would go with the Mojo.

1. If it is a pet only the mojo has a lot more color and wow factor in my opinion compared to a spider. Someone who knows very little about snakes will probably appreciate the mojo more than the spider.

2. If you are looking at breeding, everyone seems to be making bumble bees now days with the exception of the people who don't keep spiders at all. The Mojave would be something that would allow you to go in a different direction and if you are into the all white snake the BEL is a hard one to beat. If you could find one I would seriously look into getting a female Mojave though even if you have to look into another breeder to buy from.
