I need to use qualitative questionnaires for my survey which contains over 30 questions. Since survey monkey only allows up to 10 questions in free version, I am considering to take a paid plan. I wanted to ask other researchers which survey platform they find more powerful for their research purposes and why? Any recommendations which survey platform I should use for simple open ended surveys. I need to pay anyway so why not pay for efficient survey platform with several features and flexibility to reach out to today's participants.
