same times payed version and free is the same.
a friend/client have make subscribe there,we found 10-15 bugs and he never looked at them because he have 20 project active so i cant realy blame him.
you must have in your mind that you will not have any real support from him. idk if you have any support from the discord members..
my opinion is use the free version first find all the bugs and what is not working and speak with him if those are fixed on payed.
