It's not really meant for the same applications as 802.15.4. it competes with DMR, DStar, and C4FM for narrow band digital voice over very long distances (single links can exceed 100mi easily). What it solves relative to its competitors is having an open voice codec instead of relying on a very expensive silicon encoder/decoder chip while also having greater flexibility and performance. Also, if we just look at data capabilities, Meshtastic is a much more interesting comparison.
