I don't understand why would anyone use Stripe Tax? At that price range, suddenly one can also switch to something like Paddle, Gumroad, FastSpring, MyCommerce or some other Merchant of Record.
The merchant of Record will then act as a middleman/reseller between your SaaS and a consumer, and will take full responsibility not only for calculating, but also collecting and filing taxes in any of the jurisdictions.
As a SaaS, all you get from MoR is one payment at a defined schedule. Any errors in tax calculation, reporting, filing are not your problem, it's their problem.
Stripe Tax costs the same as Merchant of Record, but it doesn't do anything they do. Yes, they help you calculate the tax amount, give you the summary, but it's you that still need to file taxes correctly everywhere in the world, and it's still you that is responsible for Stripe Tax mistakes.
Until Stripe can act as a full Merchant of Record, I don't see a reason to use them unless one sells only in one (home) country.
I currently use Paddle. There have been some issues with the lack of documentation during the development, but as a developer, I'd rather deal with that than filing taxes internationally.
Gumroad is nicer from the indie developer perspective, less restrictive than Paddle regarding product types sold, but shopping card and pricing are more limited (USD prices w/o VAT only).
Stripe is still better from the developer's standpoint, more mature and nicer integration / API, but doesn't handle tax filing. Would use it if developing a product for a single market.
