Both tools are GDPR ready for European users and subscribers and both also have a WordPress plugin. If you’re looking at speed and simplicity, LeadPages would come out top.

Comparing these two tools isn’t as easy as other comparisons. Although they both let you create landing pages, sales pages and opt in pages, ClickFunnels has many additional uses. Including creating websites and building funnels. Whereas Instapage is 100% focused on landing page creation. Both tools offer a 14 day trial, Instapage starts at $79 a month ($69 annual billing), Clickfunnels starts at $97. It’s worth noting that if you purely want a landing page builder, you might not need all the functions that Clickfunnels has.
Instapage has a great editor, offers advanced personalization tools and has helpful team collaboration features, but it's also the most expensive. Unbounce also a great editor, can be used for more than just landing pages and is more affordable than Instapage $79 per month (vs $149 for Instapage).
