Still on my mind.
I'm planning to do a straightforward preservation of the laserdiscs, which I've been slowly acquiring.
Capture methodology has been an issue, I was experimenting with a standalone lossless recorder - but that didn't work out.
The primary issue is tying up my PC for long stretches while capturing, and capturing the digital audio track in sync with the video.
Regarding how best to watch it. NTSC DVDs are probably the best compromise available, albeit with a lot of dust and crap on the picture in the live action segments.
Various streaming services have a mixture of 4:3 and letterbox versions of the episode, which look reasonable, but tend to macroblock, and generally make a mess of the 60fps effects.
The Laserdiscs look soft compared to the streaming services, and not every single episode is available on laserdisc (see earlier in the thread).
If someone was going to do a restoration you'd probably take the 24fps 16:9 live action from the DVDs and the 60fps 4:3 special effects from the Laserdiscs, and somehow wedge into together in a MKV container.
For now I would suggest that you enjoy watching the PAL DVDs.
