UR44 - do newer Steinberg interfaces have better converters? Should I upgrade or stay put?

Hello,

My trusty UR44 has never let me down since I bought it in 2014.

But 8 years is a long time so I am wondering if any more recently designed Steinberg 4 input interfaces have the same converters, or perhaps better conversion?

If there are no significant improvements I’m happy staying put, but appreciate any knowledge.

Thanks,

Anybody?
