You shouldn't pick a field because of how it "looks." There are plenty of dumb biologists and engineers to go around, lol! I started in biology and then decided that I enjoyed physics more. Truthfully, biology undergrad is less rigorous than engineering, and the job prospects are worse, with lower salaries. However, biology is also at the cutting edge frontier of modern research, and almost everyone can find it interesting. At the graduate level, biology presents its own unique experimental challenges, and you might be surprised to know that there are actually many applications of engineering to biology. Every year, new developments fundamental to life itself are being discovered, and the field is rapidly changing. If you want the best of both worlds, try biomedical engineering! If that isn't an option, ask yourself what is most important/interesting to you, and follow that route.
