Recaro Easylife Safety 1st Nomi stroller Nuna PEPP Which of the above would be better for overseas traveling with 21mo toddler? Or any other better and ideal suggestions? I need stroller that can recline for LO to slp.

I suggest you have a look at all of them and go for the lightest most compact (easy to pack) one for traveling. nothing else matters when your in another country apart from your stroller being a pain to drag around and be complicated.
