Data hosting
Tally states that it is hosted in the European Union, without naming the country. AwesomeFor.ms hosts forms and responses in France, with OVHcloud, and a response stores no IP address and no respondent identifier.
Multi-person registrations
Tally has no repeatable page: you duplicate pages in a fixed number and show them based on an answer. With AwesomeFor.ms, a "how many members?" question repeats the next page as many times as needed, up to ten.
What Tally does better
Tally gives away for free what AwesomeFor.ms keeps for paid plans: file uploads, webhooks and Google Sheets. On responses, both free plans are unlimited, subject to fair use. If those integrations are what you need, Tally is the cheapest choice.
