I've used pretty much every coffee system you can imagine at this point.
Moka pots are pretty fussy as far as temp control and can be quite messy. A Nespresso is far more convenient (and IMO much better than a Keurig is to coffee). I do love Moka pots and French presses as very cheap, old tech ways of making coffee that I think are nearly as good as very pricy methods.

The best method I've found so far is to use a kettle to pre-boil the water, or get it to almost boiling at 85-90C if you have a temperature controled kettle, and then just finishing the brewing on the stove top. Almost no chance of burning the ground coffee, it's really quick to cook, and the water temperature seems to stay where it should, at least for my taste.
Don't get me wrong, it's easy for me. It's just not in the same vicinity of ease of use as a pod machine, ie. it's going to be a learning curve for most. It's not something I'd expect my elderly parents would be able to do it.
Nespresso has an advantage in the way it works as it's a pressure system. Coffee vs. Espresso.
