Tunze vs Vortec?

[Enigma]

Other than the obvious (Vortec being 1/2 on the outside of the tank), what are the important considerations between the two powerheads? I was planning on an MP10, but the Tunze controllable powerheads will connect directly to our controller.

I don't remember what controllable Tunze I was looking at, but it was comparable in price to the MP10.

Can anyone comment on the design of each in relation to critter losses?
