I also left academia to work for a company. I agree it's not all black and white. But one important thing to take into account is salary. I earn now twice as much. I'm not materialistic but it makes a big difference. It's something I didn't care about when I chose to work in academia but I'm increasingly worried about future pensions, health system and social safety net in my country. It seems to go downward and my salary as a professor wasn't enough for me to plan adequately.
