Is there a significant advantage to change from DKB to IB broker when living in Switzerland?

Hello everyone,
Would there be significant advantages (taxes or otherwise) to change from DKB broker to IB or to do new investments with IB?
If relevant, I’m holding stocks and stock ETFs, planning to invest in ETFs.
Thanks in advance!
