Strollers for twins

Sh
Okay I've asked this question before, but I'm going back between a side by side stroller and a front and back stroller. I originally wanted a front and back stroller, but I've recently been thinking about a side by side. Ugh idk what to do, there are just too many strollers out there to choose from haha. We are on a budget, and strollers can get pretty expensive. I was looking at the Chicco cortena together (probably spelled that wrong) and the contours tandem and the car seats that go with each. Those are both front and back strollers. I was just curious what you ladies chose and why. And if you have any suggestions, thank you!
