There will be
an Epic Collection later this year with the same material: the covers to the reprint issues + the adventures of the X-Men characters while their book was in reprints.
Most of the material is just guest appearances and cameo appearances in other books - it's not really a continuation of their adventures, just them showing up in other people's adventures, plus Magneto showing up to threaten the Avengers and Defenders. The only really substantial content is Beast's series in
Amazing Adventures, which is where he turned into his Beast form and meets a new Brotherhood of Evil Mutants. It's enjoyable and sets up some things that Steve Englehart would continue when he moved Beast over to the Avengers.
For the price of an Epic collection it's probably worth it. For the price of two hardcovers, probably not. It's a tour through what Marvel was like in the early '70s but except for Beast becoming a beast/joining the Avengers and Magneto turning into a baby, nothing happens that affects the rebooted series.
