Has anybody tried calculating sales tax / VAT on their own? Is it worth the flexibility tradeoff to have Stripe handle taxes?

I'm messing around with stripe for the first time, and I noticed that stripe tax isn't supported for payments via elements/payment intents.

It seems like if you want stripe to handle sales tax/VAT you have to use their pre-built solutions like checkout.

I'd rather control the whole payment flow, but I don't want to deal with a bunch of confusing tax stuff. Has anybody tried dealing with confusing tax stuff? Should I just bite the bullet and make it work with stripe checkout?
