Not drastically different however there are some nice new improvments.
Remote is very similar to previous version but a little longer to accommodate the voice button. It somehow feels subtlety nicer, with a better texture on the buttons.
It runs fast and smooth and has a few nice interface tweaks. Larger previews, refined search tool etc.
Have it paired with an echo dot and find the voice commands super useful. Launch programs, shows, search, skip episodes, turn the TV on or off, it's all very convenient. I tend to use the echo speaker rather than the voice button on the remote.
