I've had my new kitchen about 6 months now, and I have very, very few regrets. The things I love are:
Quooker Flex tap - properly boiling water, and a pull out hose too. It was mega bucks, but I love love love it!
Huge single sink - there's a lot of love on this thread for double sinks, but we're limited on space and don't wash up much (dishwater addict). The single sink we do have is absolutely huge, and it's fantastic.
Waste disposal - we have an Insinkerator, and it's fantastic. I hate dealing with food waste, so I love that I can just chuck it down the sink.
Two single ovens at eye level - I've never been able to cook two things at the same time at different temperatures before. Even something as simple as pie and chips is now possible and easy.
Pan drawers - as good as everyone else says. Love them. BUT! One note of caution: don't do away with cupboards entirely! Remember you still need places to store tall things like cereal boxes.
Tall pull out larder. Ours is only 300mm wide, but it's still great. I would have loved a wider one, but it wouldn't fit.
Induction hob. I would never go back to gas now. I find Induction so much better.
Chopping board and oven tray rack. This is a bit of a cheat, as I didn't plan it as such, but in the lift up cupboard over the ovens, I have two tray racks so I can store my chopping boards and over trays standing up. No faffing about, making sure they don't fall over just leaning up against something, or stacking/unstacking them in drawers. It's a joy! Mine are from Lakeland, and standing on some none slip mat.
