Have to say - PHIL & TEDS
Reason being:
3 wheeler, but can have front wheel fixed, or swivel, depending on terrain.
Excellent turning circle & narrow (so easy to use in shops with small aisles, etc, or getting through single doorways)
Can lie flat, semi-reclined or upright.
Can be used as a single or double buggy (for newborn & toddler or two toddlers - not twins) by using extra seat.
Travel adaptor will allow use of any car seat to turn into a travel system (ideal if nipping out to shops in town, and baby has fallen asleep in car), although recommendation of not having bubba in seat for more than 1.5 hours still applies.
Can pick and choose extras according to lifestyle, including panier bags, under buggy storage bag (really helpful, because you put everything inside it, but when you need to get buggy into car, you just pull out the storage bag with everything in it), UV sun cover, rain cover, travel bag for flights, etc.
We have used it for the last 15 months (bought second hand from ebay), and have taken it to France, used it on beaches, in the woods, in town, etc, with no problems.
Another thing is that it tends to keep it's retail price well.
It isn't umbrella fold, though, so you do need boot space, and it is heavier than an umbrella fold.
