Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FastSpring

Pricing is not published and requires contacting sales for a quote, making cost comparison difficult upfront.
As a merchant-of-record, FastSpring takes on more control of the checkout and payment relationship than a pure payment gateway like Stripe.
Revenue share pricing can become more expensive than flat per-transaction gateway fees at very high volumes.
Primarily targeted at software/digital goods sellers, so it is less suited to physical product e-commerce.

Substack

Substack takes a 10% cut of subscription revenue (writers keep 90%), plus separate credit card processing fees
