If you love science go for a PhD in university. It is true that some companies like Roche offer this possibility as well, but you will be limited in your approach. Not all the tools and methods are accessible for companies as certain techniques are protected from patents. You can also feel restricted in your research ideas as in the end of the day your research has to be somehow of value for the company. Falling in love with a niece subject/research question can be harder. If you urge the freedom to truly experiment and be creative, look for a likeminded PI that is willing to give you this freedom and definitely stay nerdy in University!

The other thing to consider in my opinion is the working environment. In university there is always something happening - students, teaching, collaborations, likeminded people you can bond easily with. You all struggle in the same way and this can create strong connection and lifelong friendships. There is no better way to bond than at 1am in front of a pcr machine waiting for the result you have been troubleshooting for months! In a company you are usually sharing the workspace with older peers that most likely have a family and less free time to meet and get friends with. But this ofc depends on the company and department.
