I'm not sure any of us know that much about prams/pushchairs at the moment, but I agree it's a bit of a 'mare choosing one! We went to John Lewis a few times and pushed all their display ones around, but it ended up boiling down to which we liked the look/colour of most. 
On a more practical note, we did make sure we got one with decent wheels and suspension for when we're off-roading with the dog.
We've gone for the Uppababy Vista in Carlin Green, which I managed to get on a deal with a Cabriofix car seat included and a free foot muff all for the same price as the RRP of the pushchair on its own.
FWIW the Oracle that is Which? says this about the iCandy Peach;
The iCandy Peach is one of the most popular travel system pushchairs around, not least because you can convert to add a second seat when your next baby arrives. Does it deserve its place as a top pushchair for yummy-mummies? We sent it for tough durability, safety and usability tests to find out .
The iCandy Peach travel system is a user-friendly Best Buy that did well in all our tests. It's a pleasure to push whether you're on smooth or rough ground, and the comfortable seat ensures your baby gets a smooth ride, even on bumpy terrain.
Second seat can be added
If you're planning for a bigger family, the versatile Peach can be updated into the Peach Blossom - this allows you to add a second seat when the next baby arrives.
You can convert the pushchair into a travel system by fitting a Maxi-Cosi Cabriofix car seat. See our full child car seats review for more details.
Reversible seat
The reversible main seat unit is suitable from six months, so we'd recommend you buy a compatible carrycot if you want your newborn to lie flat.
The seat unit has a fixed angle back rest, and the whole thing tips back in one piece with a choice of three positions; it's adjusted by pressing buttons on either side of the seat, which is quite easy to do, but takes two hands.
Adjustable hood
We loved the adjustable hood. It slides up and down to give more or less cover, and has side and rear viewing windows, so you can keep an eye on your little one from any angle.
The large rear wheels have a quick release mechanism so you can take them off quickly to help it fit into a car boot when folded. There's a useful carrying strap that allows the chassis to be carried over your shoulder, but at 14.4kg you probably won't want to carry it far.
Good for getting around town
Our testers thought this pushchair would be a good choice for a trip to the shops as it's not too bulky to use on public transport, and the large 5kg storage basket is easy to access, even with the seat fully reclined.
It comes in a wide range of fashionable colours which change every year.
