I have a Phil & Ted's. I don't mind it. My boys fight over the top though. It is a bit boring down below. I laminated pictures, put Velcro on the back, and the kid underneath gets to make pictures. The storage basket also becomes a foot basket which is irritating. I have carabena clips that I hang things on but it further obscures the view for whomever is underneath.
My SIL has bought a City Select based on my experiences. Given my time again and what was available at the time I would probably go the city select. I only ever wanted to buy the 1 pram so I picked out of the ones that could convert to a double that were available at the time.
ETA: I love that it is light enough that I can lift it easily. The wheels detach, making them a sinch for blowing up, it is easy to clean, it fits through narrow aisles that most don't, it has wheel guards (not all prams do) and it is compact enough to fit through my tiny boot opening. There are also a variety of accessories. I use the shade cloth as mozzie protection on night walks in summer as well as shade during the day. And the bum bag looking thing has two drink holders. One for parent, one for child. When you have three one gets dumped in the footwell. It also holds keys, phones and would hold a short wallet (my long one doesn't fit).
