SPICE instead of vnc

Has anybody tried using spice instead of VNC in the new 6.2 betas? If so, how is the performance and how well does the USB redirection work?

I'm currently working on setting up thinclients around my house to connect to my VMs and I'm curious how the performance is. RDP is working pretty well for me, but I cant help but try to push the limits. I'd rather not switch to Hyper-V/RemoteFX because I love having unraid running on bare metal and really don't want to venture into virtualizing it, especially under a windows hypervisor.

SPICE, care to share more info on what it is, or better yet have a link so we can get knowledge.

SPICE appears to work at least a layer above RDP meaning it provides better access to the graphics and USB devices. Its remote protocol allows you to view the screen of guest VMs and also redirect USBs from clients to the guest VMs. Essentially it is a replacement for RDP/VNC that *should* provide much better performance.

I really like the usb redirect part, that would be extremely useful
