I really like the extra space and not needing to transfer clothes when drying. To each their own though. Only Samsung is making a vented combo so far, and it’s a beast to install and drag up three stories of stairs.
Enough space for me, but you are right stacking would provide similar benefits. Don’t undervalue not needing to transfer clothes to your drier, and you never have to worry about mold and mildew in your washer.
