We went for a Jane Carrera C with a Matrix car seat for our first. It's umbrella fold, so doesn't take up too much room, and while the car seat is heavy, it lies flat which is great for long trips in the car or walks
For the twins we got a Baby Jogger City Mini Twin. It's very light, and folds unbelievably quickly, but doesn't have a car seat. There's a single version too, so it might be worth looking at.
Other than that the Phil & Ted seems good.
