The honest verdict
If trial length matters and you want firmness flexibility, Avocado is the better pick. If you know you want medium-firm and want to save $200-$400, Birch wins on price. Both are real organic builds — neither is a greenwash brand. The decision is trial length and firmness customization, not whether the materials are good (both are).
