Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Formstack

  • More expensive than form builders that only collect, which is the fair comparison for simple use
  • Document generation and signature sit in higher tiers, so the headline price is not the working price
  • The interface has accumulated features over a long life and shows it
  • Overkill where a form only needs to collect an answer

Nintex

  • No published pricing on website; requires direct sales contact
  • Free trials available but no trial duration specified
  • Multiple product lines (Cloud, K2, Salesforce) complicate pricing assessment
