Picking the "best" college

After going through the whole college application and decision process, I think it is SO overrated that people tend to chose the "best" college they got into. Rather, everyone should think about the BEST college FOR THEM. When I tell other students I'm going to CU Boulder next year, I know they associate mediocre grades with the school. Boulder is usually a "safety" school for people because they have such a high acceptance rate. When parents find out that I chose to go to Boulder over Santa Clara they are shocked. One parent I told even had her jaw drop in front of me. I think this is so unfair. Why would I go to the "better" college when it would be a horrible fit?
My mom, dad, and brother all went to Santa Clara. Both my parents were very successful there. My brother on the other hand struggled a bit. He wanted to go to the business school but didn't get in when he first applied. For the next 2 years he tried to apply to business school but never got in. He's going to be graduating in a few weeks with a economics major-which is great, but is it really what he wanted? Also, not being at the top of his class has really made job searching a struggle for him.
Having the same grades and work ethic as my brother, Santa Clara sounded like a horrible option for me. Not to mention the fact that I wanted to go to college out of state.
When deciding between colleges this was a huge factor. Do I want to go to the "better" school and potentially be stuck in a major that isn't my first choice for 4 years or have the freedom to switch to whichever major I wanted.
When I visited Boulder it was immediately apparent that I belong there. Everyone was so nice, there is so much to do, I could easily switch majors if I wanted to, and the area is so frickin beautiful.
I'm very glad I chose the best school for me and not the best school I got into.
