Just my opinion, but with all the fiddling necessary to get the temperature in the ballpark, the time needed before actually pulling the shot, the continued expense of the nitrogen capsules and such, IF one intended to use an electric device to heat water, I'd get a used La Pavoni and manual grinder. over the course of a year, you'd be about even.
As for muss & fuss...don't knock it 'till you try it.
It's pretty much as simple as boil, preheat, dump, fill, pull.
As for cost? Maybe after a year the used LaPavoni is a wash for the Mypressi + N2O cartridges (if you paid $200) but IMO the coolness factor of the Mypressi is over the top and the tiny form lends itself well to travel. In a hotel room, all you need is a sink and a kettle (or other device to boil water).
I've never tried a LaPavoni and I'm pretty sure I could learn to pull a decent shot on one, but also it seems to me that temp management with the chrome peacock is quite an exercise itself and involves careful timing and wet towels for multiple shots. The Twist seems like it would be more easily repeatable for temperature and it's pretty forgiving for pulling shots (heck - the basket can hold 20+ grams!).
But of course, that's my take and each will have their own preferences
