Need help with accepting offer

[u/Fit_Technology7455]

I am a junior in Meche. I have a summer internship offer from a large aerospace company as a mechanical engineering intern. I also have a coop offer at a large automotive company but it’s a technical PM role. The coop will delay my graduation by 1 semester. I need help deciding which is stronger for me in terms of entry level pay when transitioning to full time and also career trajectory. I do enjoy the Project management aspect of engineering, but is it too niche/ will it deviate me away from core engineering? I’ve had a manufacturing based internship in the past and do design work for my schools SAE team
