Extremely flexible and easy to use

This plugin is literally worlds apart from any other form building plugin out there.

I currently use it for registrations and newsletter subscriptions, but I will soon be needing it to collect payments (there are various payment processors available – I’ll be using PayPal and Stripe).

I full-heartedly recommend it for its ease of use and advanced capabilities. There are numerous types of fields available, progress bars, conditional logic, autoresponders, popup publishing, integration with many other apps and what not.
