It's an odd phenomenon, but when people are presented with 2 choices rather than more, they actually have a harder time choosing between the 2. There's plenty of reasons why, which is why we'll go over how to actually make a hard decision between 2, whether it's 2 jobs, 2 schools, 2 classes, 2 majors, etc.
Look at the very simple pros of each and the cons of each. Some things to consider are location, potential for learning, potential for earning, and life satisfaction. This is probably the most simple one out there.
This is a question you should ask. Say, for example, you're a software engineer and you get 2 offers: 1 at FAANG, and another at a startup. Well, if you can't decide between the 2, go with the one that opens more doors in the future. It's a lot harder to go from startup to FAANG than the other way round, so you should probably pick FAANG, work there for a few months, and then re-assess. It's actually rather simple, to pick the one that opens more doors. A math degree will allow you to do econ, but not really the other way round. A job at a large, well known firm will give you more future options than a smaller job at a mission driven company. You always have time to go to those mission based firms for more responsibilty later, so why not take the best possible opportunity now?
Don't go asking people in your personal circle. They won't be able to give the best answer. Instead, go ask people working there. If you've done an on-site with a company, you'll have an opportunity to ask about the company. Same thing with a school or major. Ask people in the actual circumstances, not people with outside knowledge.
Sometimes, you just need to make a gut decision that 1 is better than the other, even when all the facts don't line up with your decision. Sometimes, your body will guide you to your best location, so trust it.
