Hello there!
I just thought I would share my LONG experience on the subject
Only have 1 child (2nd due in 4-8 weeks) but have gone through several...
The challenge is figuring out what you need before you actually use it. With your first child, you typically do not know as you have not used this kind of thing before and so you try to do your best to find out.
Things to consider are the following:
-usage (town-offroad): here I would say, unless you are a keen trekker, or live in the countryside, reality probably means you will do 90% city usage and once in a while you will venture offroad... so try to keep this in mind
-car or public transport: for the car, you need something that folds easily, is easily picked up (handle?) and folds compact. You also need to absolutely test it in your car to ensure it fits in a way that does not take up the whole trunk. For public tranport, you need to make sure it can enter the trams-buses etc (so not too wide) and also not too long so entering elevators is ok. Of course you would like soemthing light but reality is you also very often find people to help you (at least in Zurich) but it is important to test and see if you can by yourself handle it. With our first pram, I realized during our very first trip out that because of the way it was built, I could not lift it by myself (nowhere to put hands and lift

)
-Forward and rear facing: do you wish for the pram to face mommy and then later outwards? If so, check the positions it can be put in on both sides. Our first pram in the mom facing mode would not sit up all the way and our baby hated it so we had to put her outward facing sooner than we would have liked.
-Sun shade: should be big enough to provide coverage also when the sun is a bit lower.
-Basket: if you plan to be out alot, check the basekt is a fair size and also that it is easily accessible also when child is asleep (some you cannot reach when the seat is reclined)
-Number of wheels (3 or 4?): I think this is just a matter of preference do not believe there is any particular benefit either way
-Swivel wheels: for me this is a must especially in town as it will allow you to manouver your buggy very easily
-Overall size: more than the weight I would check overall size of buggy as I believe it is better to have a slightly heavier one but compact than the other way around
-Your size: if you are tall you need something high, if you and your parter are very different sizes you need a handled that easily goes from long to short.
-Maxi Cosi adaptability: do you wish to be able to just take the maxi cosi and clip it on? I would say yes. Did not use the feature too much but incredibly handy when I needed it.
-Bassinet or not: do you want a bassinet that clips on? Or a bag for the baby to sleep? We did as I really believed that the baby is better lying down flat, and it doubles up as a bed for travelling in the first months.
A couple of other points:
-Buggy board compatible: no one told us the first time but in case you are planning more babies, try and get a pram that can fit a buggy board, this will be helpful in the future.
-Buggy vs pram: it is true that after 1 yr, we abandoned the pram and switched to the buggy. Much easier in town etc. However, we still used the pram for a whole first year, icnluding the maternity leave period of intensive usage so, even though you will most likely switch to 1 eventually, you still need a good pram for the first year.
-Buggy: here I am all for Maclaren, think nothing is best but I am sure there are other opinions

It is true it cost more, but after 18 months of intensive usage, off road and snow, plane travel etc, ours is still WONDERFUL and I will defintiely use for second baby. I would not however, use from the start as I believe babaies not to be too comfy in them.
So... we sold the pram we had for first baby and do you wish to know what pram we get now for the second baby?
Teutonia Cosmo
Tried and tested it extensively and I absolutely love it as it has everything I could wish for

We did not go fo rthe Mistral as it is a bit bigger and heavier and whilst we will occasionally go offroad, we are mainly city people
The test you posted is good but it dates from 2008 so many models may be out there now which were not then.
Also, the cheapest option is to buy online from another EU country, we chose

Make your choice relatively fats as some take about 3 months to ship.
Hope you find your happiness!
