I would advise an auto BG system for ultimate dust control and Alan L. can attest to how much difference it makes. As I said above the overall result is not about using the best dust extractor but rather having the installed system work at peak efficiency. The big advantage we have in Australia is 99% of DE ducted systems exhaust to atmosphere and thus no filters.
No question exhausting to outside would be optimal, if your climate allowed that. A total non-starter for me in Florida on the Gulf of Mexico, but don't know your location.
And yes, automated blast gates are fantastic, but I would get top-notch equipment as mentioned above first. If then there is money floating around, my Grit Automation system is the bomb. But get the air that goes into your lungs as clean as possible first.
