I read moderns in trade form, the best way for the extended storylines that are now common. You also get the variant covers as well, and one or two might grab me, but most of them I’ll just glance at quickly and move on. Alternatively, you could interpret the variant bundle in its entirety as catering to different artistic tastes, and it’s nice to see. Completists aside, for many I’m sure experiencing them this way would be enough, and at minimal cost, or without feeling overwhelmed by volume.
There are many good stories being published in the modern period and some very talented modern artists. To reiterate, as this is a common thread, when I go back to the material from my childhood, 70s Bronze, there’s a really large amount of dross there, and many of the classics don’t hold up as well now, and I find the halcyon, perfect olden days viewpoint to be a bit of a fallacy. I agree with some of the others here; buy what you like, regardless of its Age, but try to be open-minded about the process and don’t judge moderns so harshly, or miss out on some of the best.
