Otto Functionally both are 99% the same. The Metal Card is a Mastercard Credit, just like the plastic card. The differences are:
- Metal card material is stainless steel (with a bit of plastic on the back). The plastic card is only plastic.
- If you use the Easy Green plan, you get Purchase Protection and Extended Warranty if you buy things with the Metal Card (not applicable if you are on the Easy Money plan)
- The Metal Card is valid for 6 years. The plastic card is valid for 4 years. Meaning you have to exchange it less often, which could be seen as more eco-friendly.
You probably don't need both. But getting a second card can be useful sometimes, because you can link them to different sub-accounts.
