Anyone here tried Psvane 845TII or WE845?

I've tried most 845s in my home brew PSE845 monos including NOS and had settled on the Psvane 845T a couple of years back. Haven't regretted and it's for this reason that I'm curious about the newer TII and the WE versions. Are they sonically similar to the T and is the WE sonically the best or just better made (or marketed)?
