@cormacncheese Hey Cormac! Great question. The short answer is that we have a more developer-focused product (SDKs to whitelabel experience vs. widget), and work across both payments + wallets instead of just credit card processing. Let me know if I should elaborate!
I'm a big fan of http://paper.xyz/ because it's the only developer-first checkout solution for NFTs that meets customers where they are. For beginners, Paper onboards them to Web3 with credit cards and an email-based wallet. For more advanced users, Paper connects with the user's existing wallets and supports multiple tokens for payment.
