Don't forget Aqua C's spray injector method, and then there is the DIY skimmers
that use eductors or other methods to create the bubbles.

Asking which protein skimmer is the best is a loaded question Everyone
has an opinion and no one has tested every skimmer available on their tank.

From my research:
Venturi's are cheaper, more available and less efficient.
Some use a special pinwheel to chop up the bubbles (Turboflotor). You will
decrease the flow of water through the skimmer and increase heat, though
they create very fine bubbles. I had to constantly adjust my TF1k and
replacing the pinwheel was a pain and an unknown future expense when I
purchased it.
There are downdrafts that push water through bio-balls to create fine
bubbles. These seem to pack the most bang for their foot print but require
a large pump usually not included in the price (I have and ETSS 750 and it's
the best one for me so far and I have had 1 of each of the the above).
I almost bought an EV based on the # of good reviews, but decided on the
ETSS due to foot print, handling capacity, & better reviews. I don't think
you could go wrong with either myself.

om...
I am in the process of starting a new tank and I want to get a protein
skimmer. When the companies say "in the sump" do they mean that the
skimmer goes under the tank or does it acutally sit in the wet/dry
filter?

Also which is preferred, an in the sump or a hang on? Also which
brand is the best. I have a 90 gallon and I am going to use live rock.

Thanks,

Marshall
