2 DAW reasons for working with 48kHz are a slightly better sound quality; 20% more data, and it's standard with video work.

Changing 44.1 to 48 does not improve sound quality IMO, as there are 20% extra interpolated empty samples created converted files. I choose to work with 24bit, or even 32bit mostly, and stick to 44.1 kHz. Thereby avoiding extra steps and mistakes later on.
