I’d say Tassimo.
I would say I appreciate nice coffee, and although the tassimo has a lower pump pressure than the dolce gusto the taste of the coffee is a lot better than the folce gusto. It’s not quite the same as a proper espresso but it’s quick and easy and there’s a good variety of discs available, and it makes pretty good lattes as well if you prefer milky coffees .
We initially bought a dolce gusto as when I looked into it lots of people said this gave better crema and was better as it had 15 bar pump, but to me the coffee taste was terrible. Took it back ( said it was faulty!)and swapped it for a tassimo.
The machines themselves are all pretty similar, you can stop the drink early to make it stronger or add more water by pressing the button at the end. They are all on offer on websites like Amazon or argos, just pick one that has a water tank size to meet your needs. We got the T40 from argos.
