Which one do you recommend for learning SEO?

I've got myself a Semrush subscription and want to focus on learning the ins and outs of SEO as a focus point this year for my own company. I've come across the Semrush Academy however seen LearningSEO.io mentioned a few times. I'm leaning towards Semrush Academy since I've got the service however I've heard LearningSEO.io is very good. Which one should I go through or do you recommend any other ones? Ps, I know i can read all guides out there but I'd rather stick to one and complete it and then move onto another if needed.
