If you ask some designers , they do not like I2S as they feel it's not a circuit that should involve external cables. It should happen on the circuit board trace close to the chip.
Streamer output options
In my younger days, I was told so often that spdif was better than usb that it became doctrine. I'm in the market for a 2k$ish streamer and I see many higher end streamers with usb outputs that pass far higher res data than the spdif 192/24 does. My DAC takes either, but not i2s. Are the new implementations of usb now better than spdif?
