It's not a side grade, but not really a moderate one. It's good for new people, but not worth it if you have a HMD already. Unless you just want it because it's new.
That's not true all the way.
One reviewer said the lcd with true sub pixels unlike oled, eliminates sde almost nearly, and text is crisp and readable now.
If anything that's worth an upgrade. Also God beams were totally nearly gone.
Also tracking was stellar with no dropouts when controllers were below and above the player.
I'm not arguing. Just reporting what reviewers are saying.
