Delta is obviously the best airline by many metrics. Anyone that can’t admit that is in denial. That said, B6 is the best airline for me and my family. And that’s all that ultimately mattered in my decision. “Put your apps in at delta, don’t be stupid” is the first thing most unhappy guys at b6 will say before they even ask me anything about my life and learn my circumstances. It’s so annoying but thankfully of the people I’ve flown with only about 2 people said that. If On the other hand, if I were single with no children and in my 20’s, I’d probably be at delta right now. Good luck, learn inner contentment wherever you choose to go.
