I use both actually
Sunbeams on my stock Alder body 73 Jazz, as mentioned great growl in the upper mids ... that bass bass has a nice woody sound and the strings seem to bring that out.
I use the 7150s on my Geddy body with 62 RI neck bass it was a bit too bright for what I needed and the 7150s gave me back some mid growl on that bass. That bass has Nordstrand NJ4SE pickups which are a little hotter and the 7150s do have a bit less output so it was a wash.

... I like both very much.
