Have used both in the field and as long as you practice "pumping and dumping" with an extractor, the time difference is not that great. It's not like we are hunting in a herd of Elephants anymore !!!

It all comes down to having a technique on extractor models that works for you and practising it so you can do most of it without looking.

Re brass and worry about losing it.
When "hunting", the brass is the last thing I worry about,
however if possible I do tend to either make a big scrape in the ground with my foot or throw my hat down where I start so I can go back there, either to start the track if needed or to pick up the brass later.

I have a Merkel extractor.
