I've upgraded from Scarlett 4i4 to Clarett+ 4pre, for live usage (2 stereo keyboards and MIDI) and for home tracking and mixing. The software, Focusrite Control is very intuitive, and is (after few minutes of twidling) very powerfzl tool for monitoring. Sound clarity and AIR funciot on 4 Mic Preamps is superb in comparison to Scarlett.
I would recommend this audio interface if you will use it often (ex. live gigs, studio, tracking, mixing on the go, ...).
