Increasingly, I tend to judge these systems from an availability of documentation for the core SoC. It means if there's a specific problem I can go digging into fix it myself, or that the open source community can dig into the support better in general and you have fewer issues/better support in the first place. Esp with hobby development, I'd rather save time in having the system documented then $5-10 bucks on the hardware cost.
