Need some opinions on a skimmer

[AJsTank]

I am in the middle of a 400 gallon build. Sump is about 120 gallons, so about 460 gallons of actual water volume. If anyone has any other suggestions, I would love to hear them. I can spend up to about $1,000 for the skimmer. The only reason I'm really leaning towards Skimz is because I've had good luck with them in the past. I'm hesitant on that Reef Octopus, but I was seeing what else people were using on a system this size.

These are the Skimmers I'm leaning towards. I ONLY want internal.

Skimz SM251 rated 266-800 gallons
Skimz SM253 rated 266-800 gallons
Reef Octopus DCS300 INT - They say 600 gallon light bio or 400 gallon heavy
