I upgraded from an old, budget, built in and I could not be happier with the switch.
Firstly the detergent draw has a drop-down divider so that you can use liquid detergent for the main wash when utilising a pre-wash, or it can be flipped back up for powder. The detergent draw also doesn't hold water, including the softener compartment so I don't need to dry it out after every wash either.
The touch buttons for program modifications work fine, although I would still prefer physical buttons.
My favourite is the "Speed Perfect" option. It can get a weeks worth of washing through in 90 minutes. I also really love that there is a light inside the drum to help when emptying or loading. It's also great that the door unlocks whenever you pause the cycle allowing me to add missed items. The door seal also doesn't hold water so I don't need to dry it after every wash either.
It is a washer dryer, so it can't compete with a standalone dryer. However I find it works better than any other 2in1. I can do a full set of double bed sheets washed and dried in 5 hours. The are very minor slightly damp patches but they disappear in minutes.
I also didn't appreciate how big the drum is either - I can fit a full weeks laundry in with space to spare.
