I used Mailchimp's landing page builder, since it was integrated with the mailing list. Wasn't too impressed with it.
Tried carrd.io, but the templates felt a bit limiting
Haven't had experience with the other ones.
@jhlyeung Yeah, Mailchimp’s landing pages didn’t impress me either. The Carrd templates can feel limiting, but there are ways to customize them quite a bit. Still though, think the majority of people use Carrd for one page landers and bio sites.
