We use the Paddle Merchant of Record (now "Paddle Billing") with our UK company. It works well; also worked well when we were very small.
If you sell to consumers or non-VAT registered businesses, you will have to VAT-register with at least one EU member state and pay taxes there. Similar for US Sales Tax, which varies across US states (and feels extra unnecessarily complicated from my perspective). You also need to determine and validate from which country your customers are. This is a big pain. Stripe did not help with that. Using Paddle completely eliminates that.
The support and dispute resolution were also good so far.
