Cheap Audio Interface vs Expensive

Hello Gearspace community,

I am building a home music studio, and perhaps I have a naive question.

J used to have RME UFX and GreatRiver preamp, but since my UFX stopped working I now use Steinberg UR22 audio interface.

Will there be any audible difference between Steinberg UR22 and for instance RME UFX III? Given that I'll be using GreatRiver preamp (for vocals).

Can Steinberg UR22 be used professionally?

Should I invest in a better audio interface given that I still don't plan to use my studio for external clients?

Best,

Pavle
