Very cheap classes
Preply has some of the cheapest online classes. Some teachers are only charging $3 an hour which is very cheap. Italki prices start from $4 an hour. Of course, the quality of the teacher usually goes up with the price so try to check if your teacher speaks English correctly!

Disadvantages of Italki
Processing fee
When you book a class on Italki you need to pay about 4% of the amount to the payment providers(Visa, Mastercard etc). On Preply, you only need to pay $0.30 every time you buy hours.
Italki classroom
I have been a teacher on Italki since 2017 and I almost never use the Italki classroom. I don’t see the benefit over Skype and I have often had connection issues. It is getting better and I think they will improve this very shortly.
Disadvantages of Preply
No flexibility on packages
When you buy some hours with a teacher, you need to stay with that teacher. I think it would be better if you could change teacher in case there is a problem or just so you could have access to different teaching styles.
Teacher commissions
The teachers have to pay a very high commission when they start and that isn’t fair. A lot of great teachers won’t accept this and for that reason, I think that the quality of great teachers is likely to be higher on Italki.
So that’s it
The most important thing that you need to do is get started. Choose a teacher and have a class. If you are not happy with the class, then book another class. Find a teacher who works well with your learning style. Do not get discouraged, Learning English online is a little different from learning in a classroom. You need to take more responsibility for your study and your classes.
