The outsize is so much faster when it comes to vacuuming the whole room with the larger head. We bought both, compared them and kept the outsized. It’s not like you are just holding the unit in the air 90% of the time so the extra weight is ok.
My first time buying a Dyson and I went for the Gen5 Outsize thinking the difference was only the extra battery and no idea about size or weight of vaccum. It is definitely heavy. I'm a guy and can feel my arms getting sore. I had purchased the unit for my retired mom who has an injury to her shoulder and seriously considering getting a second lighter unit or selling the outside
