Combi Lightweight stroller

I need to get a stroller for my inlaws since they will be watching Michael 2x a week.
Was thinking of getting a combi one.
I actually got one at my shower but returned it bc my regular stroller (macleran) is pretty lightweight.

Any suggestions,
if you have one, do you like it
pros/cons
which one do you have?

thanks
I am thinking of getting the Cosmo DX(keylime)
or Cosmo ex
or
I had the City Savvy (I think its last years model)

any help would be greatly appreciated.

Here are pics of all 3:
