I have been using Sub-hub for a year and I can give you a real experience about this platform with its pros and cons:

PROS:
1.- The support is amazing, fast and effective. The platform is in continuous evolution, and they consider the proposals or ideas that you make and if those are reasonably affordable they update it.
2.- For conducting a website is a great tool but if you consider the integration of subscriptions, store, groups creation, etc. This makes the platform more adaptable than any other online course solution or store platform (Such as thinkific, udemy, etc).
3.- The platform is quite versatile; I use it for online courses, but you can personalize it perfectly for many other purposes since it provides: online store, forums, landing pages, etc.

CONS:
1.- Although they have conducted important and very good updates, the student experience navigating through a course, making comments, etc. is not as good as other platforms for specifically selling individual courses.
2.- You cannot follow the student evolution or provide automatically student certificates when they complete the course.
3.- You cannot automatically create invoices for the courses sold.
4.- You cannot create a multi-language site with different pages or courses for different languages even though you can translate (not completely) to another language.

Nothing is perfect and adaptable to all needs, but the balance of SubHub is without a doubt 5 tacos.
