Vitamix A3500
What works
Variable speed dial gives precise control over blend texture
Enormous container ecosystem — 20oz personal cup to 64oz full-size
Excellent vortex for smoothies and soups with tamper for thick blends
What doesn't
Loud at full speed — 90 dB is hard to ignore in an open kitchen
Tamper is needed for thick blends, which adds a step
Heavy at 12.5 lbs — not easy to move off the counter daily
Blendtec Designer 675
What works
3.0 peak horsepower — more raw power for dense, thick blends
Flat blade design is easier and safer to clean by hand
Large 90oz WildSide+ jar handles big batches without refilling
What doesn't
Less container variety than Vitamix's ecosystem
Pre-programs go straight to max speed — no gradual ramp-up
At max power, it's the loudest machine in this comparison
Bottom line
Our pick: Vitamix A3500. It edges out the alternative on variable speed dial gives precise control over blend texture. That said, Blendtec Designer 675 still wins on 3.0 peak horsepower — more raw power for dense, thick blends — consider it if that single trade matters most for your use.
