Free online survey site

I need some advice. I serve on a park board and I’m working on a survey for our community as part of preparing for our next 5 Year Plan. I need to set up a survey on a free site that allows unlimited questions and unlimited responses so the entire community can participate. With the help of HubSpot, I’ve narrowed it down to 2 sites, those being Survey Planet and Google Forms.

Does anyone have advice on a these two sites or maybe different site than these?
