Beast Mini 600 Plus vs Ninja BlendBoss

Both are single-serve blenders rated 4.6 out of 5, but they are built for different jobs. The Beast Mini 600 Plus is the better pick for smoothies and everyday blending: three Tritan vessels, a leak-resistant straw cap, a 2-year warranty and owners who say it replaces a full-size Vitamix. The Ninja BlendBoss has more power (1,200W), three Auto-iQ presets and a cupholder-friendly 26-oz tumbler, so it wins on ice and frozen drinks. Ninja owners report mold and residue building up under the blade gasket, and its warranty is one year.

• Choose the Beast Mini 600 Plus if you want smooth, portable smoothies in three vessel sizes, a longer warranty and easier cleaning.
• Choose the Ninja BlendBoss if you crush ice and frozen fruit often and want automatic presets and a tumbler that fits a cupholder.
