I've never had a sxs with ejectors, the extractors work fine, but my o/u have ejectors and that works fine too. I believe if i was in real trouble I'd prefer ejectors simply because it's a faster reload, BUT you are going to pay lots for for a sxs with ejectors. Example neither merkel or krieghoff have them and say they'd have to redesign to get them. This leaves you with paying lots for money for a questionable thing.
