Primer on X-Men on Blu-ray

[Lynos]

Hello folks

Now that Dark Phoenix, the last film in Fox's X-Men franchise is out, (as an independent studio, that is...), I would like to get the whole series on blu. I am only interested in the main series, so the original trilogy from 2000-2006, and then the second series from 2011 until DF. No Origins, Wolverine or Deadpool flicks. At least not for now.

There has been many releases over the years, it seems. The Steelbooks caught my eye. They have great artwork, and are cheap at 25$ for three movies.

However, there also 4K releases out there.
And then there's The Rogue Cut.

I'm looking for any knowledgeable people who can give me some advise on this. For example:

- are the expensive 4K releases worth it? And if so, which ones? Some of these were filmed digitally so I'm not sure the uptick is worth it. I do not own a 4k player currently but hope to soon.

- is The Rogue Cut worth it? Does it have any other unique special features (except for the new commentary?) And is the new cut itself significantly changes the film? Is it worth breaking the sets for? Or are there any boxed sets that include this release?

- Buying boxed sets is nice, but since i plan to add Dark Phoenix as well, it would not look very uniform on the shelf, so perhaps individual titles are better? Do you think it's not worth it financially?

I am buying from Amazon so anything that is a Target or Besy Buy exclusive is not relevant to me.

Thanks in advance!
