I've tried 5.6 Luna many times. I don't think it's any better. I definitely use it from certain tasks, but I find it the most susceptible to that conspiracy theory example I gave above.

I didn't love any of the 5.6 models, but weirdly I think I liked Terra the best. I still wouldn't call it amazing though. I'm still very happy with my codex plan, but 5.6 just wasn't my cup of tea I guess.

Definitely giving 6 Luna and Sol a try this week though.
