I have tried teachable, thinkific, Learn Dash, AmemberPro (years old), Digital Suitcase, (something close to that), wordpress member plugins, Optimize press and so on. I current have thrivecart learn +. This blows them all way as a whole.

1) The big names won't let you multibrand. I'm not greedy, I have two main brands and a couple of sub-brands I want to separate. (we all do). I would need an account for each elsewhere. ProductDyno allows me to have all 4 on their own domains. So I can use wordpress (which is still the best front end) for each domain and put PD at subdomain.Domain.com. Job done. All brands sorted. In t3 I can do that 20 times.

2) I think up a product name that does not fit anywhere or I just want it to be featured. OK! Would need a new account elsewhere. Not with PD. login.SpontaneousProductDomain.com ALl in the same account. I can do that unlimited times.

3) The onboarding robot takes you through every page. I think I can train an admin just by having them login. Huge!

4) I integrated Amazon s3 in 10 mins. I can cancel vimeo now. $20/mo.

5) Doesnt have a front end. This is not bad, I can assure you that there are risks to building your whole stacke on someone else's land. I always make the main public content on wordpress and backed up. This way I keep all the link juice and google rank for ever. The tricky part (LMS) productdyno does amazingly. if it ever goes away, I just have to change login.mydomian.com to a new provider. But judging by how good this is I think it will be around.

6) Landing pages would be nice but again see point 5. Hosting is fast these days and wordpress is gotten much better so building ones own landing pages on ones own land is still pref3rable.

7) In integtrates natively with Thriecart. Easily the number one funnel focused cart.
8) Intereates with so many email provides, most will find what they need.
9) Member area templates. I really like this. I have some courses that are multi-media and some are multiple short videos. This allows me to match exactly.
10) WOMBAT - get this. Your community will help you grow.

The only thing I would like is I would like the single product area to function like shopifty or wordpress. I can put all my small products under 20 bucks in there, I have around 200 "scripts" and I can make it like a shopping cart. With discounts for buying. I will still need to use woocommerse for this. But other than that. This is the solution I have been looking for. Try to think of it as Learn+ on steriods! Im sure many will want a site builder and that would make it better than teachable. But I dont need that for reasons stated. ANyway, this is the one for me.

Lastly, check out how responsive Fraz is. That is a great sign of a team leader dedicated to the job. I say get it now.
