The “uncertainty” is between the ACS and the Nurri, at this point. I really dislike the aesthetics of the Profitec (it seems a big square box to me, even though the footprint is smaller than the other two).
The size thing is interesting:
ACS 368 × 508
Nurri 360 × 580
Profitec 339 × 505
The Nurri is the largest, but because of the sloping profile it seems (in photo - haven’t seen any of these in reality) smaller.
