Return pump

[NucMed]

I am setting up a 110 gallon with the same footprint of a 75 and 90 gallon tank and have an acrylic sump from eshopps. I need help deciding on whether to just use a submersible return pump or drill a hole, place a bulkhead, and use an external pump. I'm leaning towards external but never used one before. I used to use Mag Drive for submersible but technology I know has changed. If submersible what pump and if external, what pump. Any advice would be great appreciated, thanks.

I would do a submersible Eheim 1260. Save space in the cabinet and one less thing to cause a leak.
