Just bought the mamas and papas.
DH may have a stroke but it's my biggest splurge and it's my 4th kid so generally I make more conservative choices. I put my nearly 4yos in it - one is 32 pounds, one is 42 - and it still pushed dreamy. The seat is deep and tall enough that they are comfy. I didn't find the seat to be small. The footrest situation was a little weird, though.
My girls both liked it. Tried the Indigo with the girls in it and holy cow it was god-awful. I don't expect to use the stroller with a kid this large but it's nice to know when it gives a high weight limit it can actually live up to the claim. And the M&P seriously pushed NICE even with my girls. (The First Years seat is not as deep, either - I felt like the height was about the same)
The seatbelt isn't quite what I'd like - I prefer a 5 pt that can be 3 pt as well, which I thought this was, but the top doesn't detach as I thought. But we can make due and just do the waist part like on my Bob. I think 5 pt harnesses are overkill in strollers - some kids may need them, but I prefer it to be optional. I think that's my biggest nitpick. SUPER easy to fold, though it can only be folded with the seat facing forward - but it is easy to flip the seat so no biggie.
The seat actually RECLINES, doesn't just tilt, which is nice.
FWIW I tend to take Baby Gizmo with a HUGE grain of salt... I'm kind of skeptical of her foray review... I feel like she is inclined to be more positive than negative, which is understandable if you want people to give you stuff to try, but not helpful if you are buying.
