Definitely Yeti. Have had mine for six years and have dropped it on concrete/rock more times than I could count. Just one dime sized dent on it. The newer ones aren’t so heavy, but definitely more so than other options. Nalgene does not insulate so you can’t leave it in the sun or put hot liquid in it, which renders it useless imo. Hydro flasks dent all to hell, but I believe they’re cheaper than Yeti.
