All of the Adobe's suggested alternatives are good form builders. If you're looking to save a lot of time switching to another form provider, Formstack has a form importer that will rebuild your Adobe forms for you. https://www.formstack.com/features/form-importer
Formstack has lots of other features and data integrations as well. The pricing is a little higher, but you receive lots of form features. We have many universities that use Formstack and take advantage of features such as:
- Approval Workflow
- Electronic Signatures
- Social Autofill
- & Multi-user accounts
I work for Formstack and would be happy to put you in touch with our business development team to see how we can help you grow.
Hope this helps,
