Virtual Wheel Slip? Only Neo? And new trainer advice

Just wondering if the neo is the only trainer subjected to virtual wheel slip? I know this was rectified with the 2T but was wondering.

I was going to upgrade my snap to with a Saris H3/Kickr Core or possibly a Kickr 18. With the saris/core I still need a cassette and tools to put the cassette on which means around $900 where the kicrk 18 would be $1000 with everything installed.

What are your thoughts?
