Best Blenders for milkshake quality

#1 Vitamix Ascent X5
3.0

Vanilla shakes are frothy, but one side-by-side test found slight curdling and separation even on the X5.

Pros: overall satisfaction, blending performance

Cons: value for money, noise level

#2 Vitamix Ascent X2
2.5

Milkshakes turn frothy but slightly curdled and separated in a controlled test. The X5 produces a slightly better result.

Pros: overall satisfaction, ease of cleaning

Cons: noise level, usable capacity
