For any addressable light system for a tree or bush I would recommend getting more lights than you think you need.
My personal christmas decoration consists of a charly brown christmas tree with a single ornament on it. It started as a joke (and convenience for ongoing construction), but it became a tradition. I truly appreciate the zen nature of unfolding it into an appealingly broken pattern and also having just a single ornament.
I have no intention of swapping to Twinkly for my normal accent lighting around the house - btf-lighting.com + WLED is still your friend for that.
I wish there was a bit more customization. Particularly around the flashing effect. Also, oddly, the color settings are HSV, but they don't give you the V, so you can't get a clean grey color. I wanted dim white lights with sparkle flashes, but I haven't been able to make that happen.
