Bashsea or Biotek sump?

Give me some feedback everyone! Bashsea or Biotek for a sump? Royal Exclusiv is nice, but I'm not excited about shipping to the US for such a beast. Both have large skimmer sections, which is important as my skimmer has a large footprint.
Also, internal pump or external? I have a brand-spankin'-new Reeflo Barracuda/Hammerhead I could use, but I'm not excited about drilling a sexy new sump.
Any recommendation on the sump and pump would be appreciated! If you vote internal pump, can you give me some good, better, best options? Display tank volume is 320 gallons with another 300 gallons in frag tanks, refugium, Rubbermaid tubs, etc.
The sump will be primarily used to house my skimmer and make access to other equipment easier than digging through stock tanks.
Thanks for your help!

 

I have always been a fan of bashsea. I have had 2 of there sumps. The detail and craftsmanship is top notch.
