The benefits that I personally have reaped from studying calculus justify the time and effort that I personally have invested.

I'm not qualified to guess how universal my experience is.

I personally enjoyed analysis for its own sake. The calc sequence was a bit silly, like a cookbook, but there are some cool ideas in there that I still enjoy thinking about. Math maturity that came out of that (and others, especially number theory) has served me well as a conceptual framework in all kinds of disparate areas of my life.
