Well, the combo whoring Qum + not saving Carina's men means an extra 25,000 ProN, which means you can invest in the exact same things than in your normal route AND don't have to ask Megail for money, which in turn provides an extra 200,000 ProN after the reunion (100,000 from Megail, 100,000 for having invested in the Eustrin Processor using the extra 50,000 for Megail route), which, with some extra shenanigans, can convert into investing in one more bank, which gives a lot of extra money for the last investment phase of Chapter 3 and Chapter 4.

But hell, still not worth it in my opinion. TLS is a game about harsh decisions and sacrifices, and I'll gladly make Chapter 4 harder for Qum/Carina sake.
