Esmae my biggest requirements is the machine must be easy to maintain and is going to last for many many years if looked after well.
The group on the Minima requires zero maintenance. All you need to do is to backflush chemically every week, and clean the shower screen.
On the MaraX, if you do that, you also need to take the cam lever apart and lubricate it. It takes 15 minutes when you get good with it, and it’s not really a bother once you incorporate into your routine. But, unlike the Minima, you only Backflush chemically every month or so.
The Minima will give you consistency and the ability of turning the service boiler off for when you don’t want a milk drink - this is exactly what I do with the Elizabeth.
