SEPA bank transfer from UBS to another SEPA account should cost max. 0.30 CHF (but free in some banking packages). If you do the payment from ZAK, it’s free. So you can save 0.30 CHF per payment with ZAK. Maybe. Depending on your UBS package.
Are you going to fare better with ZAK? Maybe, maybe not. It depends on the currency exchange rates and costs for currency conversion.
This will most likely be the main factor in terms of cost.
Neither UBS nor ZAK will be particularly cheap on that.
Generally, using a non-Swiss intermediary or account (such as Revolut or TransferWise) will be less expensive for currency conversion and thus likely less expensive overall.
In your particular case however, Binance as a cryptocurrency exchange (i.e. “high-risk” beneficiary) - or any sending payment providers - might not like you sending from a non-bank account and/or an account not held in your name (it is in fact prohibited by TransferWise AFAIK) for compliance reasons.
