I just had a 320 harrowed raid sniper drop this week. It has firefly so it's fantastic for regular enemies but I found at oryx my 310 eirene (either 310 or 307 I can't remember and am on my phone) felt like it worked better against the ogres because the impact difference staggered them more. Using the raid sniper did damage but I never had one stagger so they got significantly closer to the middle of the map than with my eirene where I could keep them in the corner.
