The only Big 2 thing I'm still reading is HiX-Men. It's totally different from what the average X-Fan liked before the 00s and the influx of moviefans, but I like Hickman's brand of writing and it's an enjoyable SyFy book. Honestly, no matter which way you cut it the average Capebook is pretty bad and we're attached to them because they remind us of periods of our lives. They go through the same motions and nothing really progresses or has any meaning. I'm slowly trying to build an Omnibus/Absolute/HC collection, and I watch all those guys with whole rooms filled top to bottom with 100$/book of capes and I just don't see the point. It's all a mess of genres and titles and nothing stands out. Nobody will notice your Sandman Absolutes if they're surrounded by tons of other things. I'll get a run per character/team to represent them and that's it. Stuff like Sandman, Lucifer and the such, self-contained stories, I genuinely want. With X-Men, Spider-Man, Batman and the such, it's more of a case of "just buy the damn thing to put it on the bookshelf" than genuine interest. As time goes on, I find less and less fondness for all of them. I have some favourite runs, some favourite characters, but I find that I like the concepts more than the execution.
For my money, Marvel is better in that regard as they do more reprints and have more options. You have the Omnibus, then you have the Masterworks which slowly cover entire runs, and you also have the cheaper Epic Collection TBPs. DC has the Absolutes that look really cool, but they don't collect as much stuff in such formats and editions.
