Internal vs external streamer/storage on Mytek Brooklyn

I am trying to build my first audio system (so far I used SMSL M7) and I am confused about the sound quality on Mytek Brooklyn. Should I go for the Dridge with a SSD attached, or an external solution like SoTM Neo Ultra or ProJect Stream Box S2 Ultra would sound better and Brooklyn DAC + would do?
I am asking now because I can get a 200 Euro discount on ProJect Stream Box S2 Ultra and it would be a good time to get one if it is a superior solution then the streamer inside Brooklyn Bridge. Thank you.
