Yeti Rambler vs Hydro Flask
Both keep drinks cold all day. The lid is the real difference.
The short version
Both are vacuum insulated stainless steel and both work. The practical difference is format: a tumbler fits a cup holder and suits a desk and a car, while a wide-mouth bottle carries more, takes ice easily and seals properly for a bag. Buy the tumbler for desk and car use; buy the bottle for carrying around.

Choose the YETI Rambler 20 oz Tumbler if…
They drink coffee at a desk or in a car. A tumbler is the right shape for that and fits the holder, which sounds trivial and is the single most common reason one gets used daily and the other does not.
Choose the Hydro Flask Wide Mouth Bottle if…
They carry water around all day. A sealing cap means it can go in a bag without incident, and the larger capacity means fewer refills.
Common questions
Are these dishwasher safe?
Many current models are, and older ones often are not. Check the specific product, because putting a non-dishwasher-safe vacuum flask through a cycle can damage the seal.
Does the brand actually matter for insulation?
Both perform well, and the gap between premium brands and decent cheaper ones is smaller than the price difference suggests. What you are largely paying for is build, lid design and warranty.
What size should I gift?
Around 20 ounces suits desk and coffee use; 32 ounces suits all-day water carrying. Larger bottles are heavier than people expect when full, which is worth considering.
