More or less the same performance.
Get whatever comes cheaper and with better support in case of malfunctions.
Personally if money was not an issue I would get Gavitas.
Samsung make LEDs, and Gavita assemble light units using LEDs.
I have no faith in Gavita as a brand, and no idea what they are using. However, I don't know who is making the 301 units either, or what they might be blended with.
I do know the 301 is technically a good LED, and Gavita is a label I have bad experience with. Making this a poorly weighed up, but easy decision
