In my experience, I would never use Paypal again, they are thieves who think your money is theirs...
Not to mention that as soon as you have exceeded €2,500, they will start demanding a lot of senseless paperwork, in fact they will block your account and keep your money until you give them what they ask for.
Also they will return the money to any idiot who requests it and you will lose sales (although this also happens in the others, I think to a lesser extent).
It is also true that I have never used Pionner, I have been using a bank transfer for a long time and I have not had any problems, also there are no fees for receiving your money. So I can't tell you much more.
