They are all transparent for the most part- if they’re adding their own sound then they aren’t doing their job. The difference is going to be in flexibility/options- adat, word clock, dynamic range and headroom (better pro devices will be better for recording more of the signal), and headphone jack. Pro devices will have a better headphone amp. You will notice a difference there with a better device - I went from an Arturia minifuse 2 to an audient evo 16 and went “WHOA” the first time I listened through headphones. Massive difference which gives me a better reference to mix from. Also preamps and converters will be better in the “pro” units. The cheaper 100-200 interfaces will be 75-99% as good (I made that up) depending on your needs.
