Best audio interface for doing simple guitar/vocal recording?

Focusrite Scarlett 18i20 (Gen 3)

Eta

Whats your budget? Cause with that one it'll be everything you'll ever need. You could multi mic a lot in the future, like an entire drumkit for example if opportunity arises. I know you said simple..but still.

Focusrite 2i2 is all you’ll need. Mine has served me well for years

I’ve struggled with making this decision for years and always come back to focus rite scarlet but that’s all I can budget given my limited recording experience. I’d love to plan to scale up like Clint suggested,
