I really like the blue one! Think you've done great on the blending of the petals. 😊
My mum made me sell my Gameboy Colour, which was still in great condition, for a 10er at a flea market. Still get sad about it any time I think about it... Was my first ever console and probably the reason green is my favourite colour now.
I'm not sure on the privacy side cause I didn't really look into it, but for content in theory you should be able to pretty much see the same content on either site. In practice kbin is still very new and has some issues / is slow with federation. This means you currently will see more posts on lemmy than on kbin.
Personally, I like kbin's design better and use it more (if you're on mobile its mobile browser site looks great and can be used just fine until we get an app for it). If I run out of new stuff that interests me on kbin I switch to lemmy to catch all the stuff that didn't show up on kbin.
