The M&P Joolz / Joolz Day is essentially the same pushchair. M&P made it for some time and Joolz took the rights back (or something similar) and are making it as the Joolz Day now. There are minor differences - I have studied them in the past and concluded there wasn't enough to really quibble over. The main one seems to be that the Joolz Day seems to be lighter than the really heavy M&P one.
If you look at the side of the chassis a Joolz Day has "Joolz" written around the top of the joint where the handle extends. The M&P ones have Mamas and Papas written down the side. I might be wrong but I think black ones are Joolz Day ones too. I have seen some M&P ones without writing down the sides too.
I know a couple of MN here love their Joolz Day pushchairs, and it is beautiful to push. However I see it as a "walking" pushchair - one to walk out of the house with. To put it in your car, compared to other pushchairs, I find it big, heavy and bulky TBH. But the seat is enormous - the footrest extends. I find the basket hard to get into and tiny. But the big shopping basket is good.
Anyway to answer the OP question.
Pushchairs go into categories for me and "buggy" is a lightweight stroller, usually FF, and often umbrella fold. Wording I know is subjective and I am guessing because you want PF you mean a "pushchair" ie a good strong, nice-ish quality chassis with a seat which goes both ways (usually on a frame).
The reason I distinquish is to try and compare like for like IYKWIM ie a City Mini is excellent, but not in this group. The Joolz Day, Vista, Cruz and Xplory for me fit into that pushchair category for me.
So, on that basis, the one pushchair I come back to time and time again for easy of use, and yet looks great, is the iCandy Peach. It ticks every box I have - large, comfy seat, easy to fold, small folded, large basket, gorgeous to push etc etc. plus it can become probably the best tandem there is for two little ones. The downside is the raincover, but there's plenty of alternatives out there.
The other pushchair I really like and I think is good value for money, is the Baby Jogger Versa. The spec is really good and you get a lot for your money, plus a lovely pushchair to use and push.
They both work really very well. I think if you dont have the money for the Peach, then the Cherry is an excellent alternative too.
I always say the Vista is probably the best spec pushchair on the market, but I just dont warm to the more angular shapes and I find it large when folded. It took up a lot of my floor space and we didn't have room to keep it.
The Bugaboo Buffalo really excites me though. I like Bugaboo's a lot, but each pushchairs has its strengths but also its weaknesses. On paper, the Buffalo seems to take all the strengths and has removed or ironed out the weaknesses. I think it should be pretty perfect as a pushchair goes! I think the Cameleon, Donkey and Bee are all excellent in their own ways, but all have downsides. But I have / have owned all, and would have them again in the right circumstances.
of being a buggy user I have settled on, and am happy with, a Mountain Buggy urban that gets used mostly for walking out from the house on school runs, dog walks and local trips to shops and vets and whatever (i.e. quite a lot of use). In the car I have a Maclaren Techno XT that gets used basically everywhere we go out and about shopping, children's activities and suchlike. If we go in the car for a walk or something we do take the MB. The only thing is that neither are parent facing which I would prefer but have never come across a parent facing buggy that I like as much so we do without.
