I'm not trying to start a war here, just wondering what your takes are. They pretty much have the same concept of lightweight desktop, but with different toolkits.
I'm a KDE person myself, but I've had experience with XFCE.
I've tried LXQt in the past but never really gotten into it, perhaps the timing was just not right.
I feel the same, though having more options for lightweight DEs is better. I came from gnome 2 after Ubuntu switched to Unity DE back in the day. Xubuntu ran nice on all of my kids low power devices and it became my desktop as well ever since. It's just as happy on my work laptop as well as Ryzen thread ripper with 3 rtx4000s and 3 magewell hdmi capture cards we use for visualization at work too. It really feels like a solid DE with less fuss than most.
