I think the bottom line is: "to each his or her own." I think that the most important thing one should consider is to do whatever is truly right for you. Whether this is academia, private practice, Kaiser, the VA...or even non-clinical work, you should pursue what will truly make you happy. Many studies have shown that happiness does not significantly increase after a certain threshold, and I personally agree with this. I don't feel that much "happier" making 7 figures compared to when I made low 6-figures. What I'm definitely more happy about is having autonomy compared to the past.
I think the hardest part of deciding, is that when you are in training, you are primarily surrounded by the academic practice model. At least when I trained, there was constant pressure from our attendings to pursue an academic career. And there was this unsaid sentiment that private practice was a waste of one's intellect or not as ethical as academic medicine. There was a lot of self-righteousness, even though when I reflect now, there were/are many bad surgeons in academia. I know I would have been miserable in an academic practice. Though I liked research, the number of hours I put in to publish each manuscript did not seem worth it to me. I also despise bureaucracy and love that I can change the way I practice (e.g. equipment, staff) in a heartbeat. I didn't want to sit through committees to improve things for my patients. Anyways, that's my 2 cents. Just make sure that whatever you choose aligns with your heart.
