I transfer quite a bit of money to our freelancers all over Europe and SEPA has served us very well, I'd definitely not use a service like TransferWise over regular banks for such payments, and that's besides the ease of integration with our accountants who can now easily match up invoices with payments from the current account.
I understand it as a business but sadly banks in e.g. Bulgaria add extra fees on top of SEPA transfers which you can sometimes avoid and sometimes not.
