I recently had to consider this and was quite surprised to discover that the US was the best place. Compared to most countries the US has been a tax haven for a long time, but the 2017 tax change meant that in most cases the US would be a significantly cheaper place to recognize revenue.* Also the mechanics of getting the boring things done is significantly easier, as noted by the Germany post cited in your question.
Because of the US FATCA law you may have trouble opening a bank account in some countries (smaller entities simply can’t be bothered with the paperwork the US demands on accounts for “US Persons”, a term which has specific meaning). In practice this just means you have to deal with larger banks.
Note I’ve been a US resident for decades, and started several companies here, but am not a US citizen and have lived and worked on three other continents as well so had no prior bias.
* Note 2: this business is intended to be quite profitable relatively soon, rather than a “focus on user growth and toggle the profit switch later business.
