Any Feedback on two different skimmers????

[Mekinnik]

I would like any feedback on a Berlin Hang-on skimmer and a CPR Bak-Pak. I am going to replace my current skimmer and am unsure which one to go with?

40 gal.
25 lbs. LR
1 1/2" SB
1 blue chromis
1 green spotted mushroom
1 star polyp
various snails and reef crabs
1 peppermint shrimp

I originally bought a Aqua C remora a few months ago and ended up returning it due to noise. Ended up getting a Cpr BakPac and I am very happy with the results. Very quiet.
