Indeed, the problem with the budget Scarlett interfaces is that if you use both inputs (L/R) .. that's what you get; one input on the right side and one on the left.
So if you are recording a Mic and anything else, the 'anything else' will have to be a mono track.
The DAW will either give you two mono tracks, or a stereo track with vocals on one side and guitar on the other (not ideal).
Configuring the DAW for the target track(s) to be Mono is important, and even then not always optimal.

Once you get above the 'two input' Focusrite models this issue goes away, and you get more software control (a mixer) that doesn't come with the lower priced models like the Solo and the 2i2.

They do a fine job otherwise, but your options become a bit limited for the couple hundred you save.
That said, I do have a 2i2 that I keep for any 'get to a location and record real quick' scenarios.
They are handy and can record quality tracks, but I prefer more options for most of my needs.
YMMV
