ClickFunnels invented the modern funnel builder and remains the deepest tool in the category — if you're an info-product seller doing aggressive paid traffic into long funnels with multiple upsells, the depth here matters. Email + membership + community are afterthoughts.
Kartra is more balanced — funnel building is good (not best), email automation is solid, the membership module is genuinely useful, video hosting is bundled. For a creator running a more integrated motion, the all-in-one math wins.
