Keenz airplus 2.0 vs baby zen yoyo+

My 10mo baby loves to sit upright to view the surrounding. Would you recommend keenz or baby zen (plus guard bar addon from Shopee)? Which stroller is better in the long run? Is keenz seat too narrow for bigger kids? Which is easier for mummy (alone) who takes taxi alone to fold up and unfold while carrying baby? Does baby zen topple over easily if i add a baby bag at the handle?
