The counter’s vote
The GS3 MP is the one the crowd demonstrably buys partly for its looks — we report the vote; the judging is yours.

“Its gorgeous design, pressure profiling paddle group, mammoth capacities, optional plumbed operation, intricately thoughtful features... raise the GS3 to its position at the highest echelon of home espresso machines.”
“The R Nine One is Rocket's flagship for people who want pressure profiling without hacks. It marries a saturated brew path to dual stainless boilers and a variable-speed gear pump.”
