Really the only improvement from your Mara that you’ll see in the cup if you’re not into any kind of profiling is going to be from a saturated (or similar) group.
For that you need to spend a fair bit more (that Arkel machine has one apparently).
Anything else is really only likely to aid efficiency of making milk drinks, be slightly lower maintenance and be a sort of ‘sidegrade’ rather than an upgrade.
I would say save the money and spend it on good coffee instead but seems like even that’s becoming harder to find lately.
