I have the P & T Sport (with double kit and Lazy Ted). I find the brake annoying because like you say it is difficult to sort if you are wearing jandals, and it also wakes the baby.
The foam handle isn't going to last long because it touches the ground when assembling the pram (or if there's a way around that, I don't know it yet).
I like the 'travel system' idea using the capsule and frame to clip onto the pram. We have the high-sided capsule - I would say get the normal one - the HS, one the babies feet stick up at an uncomfy looking angle.
The pram doesn't come with any liners or covers like some brands - but I bought some cheap generic ones from Farmers and they do just fine.
Tip - if you live in the country keep the tyres a little soft for use on gravel roads/paddocks for 'suspension'. DH keeps pumping them up grrr!
That's all - I haven't compared/used other prams so not sure what the other brands are like.
