I think this is a pretty well-reasoned piece, personally. The clearest thinking often happens when we are confronted with two already pretty solid options and asked to choose between them.

With only the information I have in front of me, I would have chosen Offer 2. More money is awesome in a very straightforward way. Staff is more fun than Senior. But mostly I think my view simply is that boring, steady businesses which can afford to pay top dollar for top talent tend to be really good places to drive capitalism forward at compared to relative moonshots like fusion tech. It seems like a much more straightforwardly good value proposition to (letting my brain fill in a random high impact detail here) bust my ass to shave a basis point off of everyone's Vanguard management costs than to work on something like fusion, where I imagine plenty of very motivated people are already exploring this from a lot of different directions.
