EY Business Advisor Program, KPMG Financial Services Solutions, or BofA GWIM

So I have 3 job offers and I'm really struggling with which one to take. I am a senior at a target school studying Business and have internship experience in Corp. Fin. and Wealth and Investment Management for BofA. The salaries are all pretty much the same except KPMG is about 5k lower than BofA and EY. BofA also has a 10k signing bonus while KPMG and EY only give 3K. BofA's offer is in the Global Wealth and Investment Management program (which I think is a little boring at the entry-level stage and I just don't think the training is enough to really accelerate my career, I also interned there for the summer and enjoyed my time but got bored really quickly and just felt I wasn't learning that much). I also feel like people don't respect you the same when they hear wealth management. Like sure, if you are managing a huge book of business then okay but entry-level you are doing administrative things and cold calling a ton. The EY and KPMG jobs are pretty similar, they are both in advisory for Financial Institutions. So basically consulting but specifically for banks. EY is the Business Advisor Program for the (FSO) Financial Services team and KMPG is the (FSS) Financial Services Solutions team. I have also had a hard time distinguishing any actual cultural differences between EY and KPMG even though I have talked to a lot of people. Everyone just kind of says the same thing about how amazing the firm is (I feel like Big 4 are not that different from each other). Since this is my first job out of college (and I want to get an MBA from a top-10 program in a few years) I pretty much care about 3 main factors: 1. Best Training (I really care about having a long term career in Finance and I am excited to work for a company and in an industry where I can really learn a lot) 2. Salary 3. Company prestige in order to get me to a top business school.

Please help any opinions are welcome, I'm really unsure what to do!
