All things equal, pick the areas with growth. Google, Meta, Amazon all have natural monopolies in growing markets where your individual performance doesn't matter that much. This is a safe play w good short term upside. AI, blockchain, security, etc are growing areas but you need to make an initial investment and maybe a lateral or down move to retool yourself and reorient your work network. This is the risky play with a lot more potential upside.

Life is short though, once your base needs are met, figure out what you want to work on and spend more time on whatever that is.
