Still rocking my Galaxy Watch 4 and don't see a need to upgrade yet. Battery life isn't great but I've grown used to taking it off in the evening and letting it charge overnight. Who's eyeing the new Galaxy Watch 6?
The 2GB of RAM could be transformative. I love my Watch 5, but the main complaint I have is even if all you're doing is using one app and the home screen, it really struggles with smoothness in transitions and responsiveness. A doubling in RAM could be what it takes to improve it.
Shit I was worried when I bought the 5 Pro that they'd bring the clicky bezel back, but figured it would be something they commit to doing (moving part=failure point).
I bought the Galaxy Watch 4 Classic for the bezel even though the 5 was out. I just needed a stopgap until the 6 came out. As long as the reviews are promising, I'm excited to upgrade. That said, the 4 is working just fine and I haven't run into any limitations.
