Hi!
I would, mainly for an older toddler, consider the backrest length as the main factor, looking at those models that sport a high one. Also, since this type of pushchairs/buggies usually doesn't feature an adjustable handlebar, I would be careful choosing one that is at least slightly taller (than average).
From the more affordable ones, I will suggest the CBX Etu Plus - its backrest is whopping 52 cm! Also, from the more expensive ones, the Cybex Eezy S+²also has a nice, spacious seat for its type.
Comfort- and canopy-wise, the Ergobaby Metro you mention is certainly a very nice choice. And if the style is also a big factor in your decisionmaking, I would certainly look at the GB Qbit+ All-City (it's one of my personal favourites, I simply love its design ad functionality). From these, pick any that you feel like liking because they're all very good choices for you.
