Which is better for commuting with a bag?

The Yeti. Its quick-flip straw lid is stated 100% leakproof, and it has a welded handle. The Thermos lid is not stated leakproof, so keep it upright.

Is the Yeti worth the extra money?

For $5.60 more at the best new price, you get 4 oz more capacity, a leakproof straw lid, a handle, dishwasher cleaning and a five-year warranty. If you only need a desk tumbler, the Thermos is enough.

Which holds more coffee?

The Yeti holds 20 oz and the Thermos holds 16 oz (470 ml). The Yeti gives you about 4 oz more per fill.

Which is easier to clean?

The Yeti is dishwasher safe. The Thermos is not, so it needs hand washing, and its screw lid has fewer parts than the Yeti's straw lid.

Does either fit a car cupholder?

The Yeti is stated cupholder compatible. The Thermos listing does not state cupholder fit, so measure before you buy.

The Yeti carries a five-year warranty. Thermos states no warranty for this mug, so long-term coverage favors the Yeti.
