So with DC universes expanded comics collection has that been enough to make Yea Forums consider getting a subscription...

You're paying for access to a library. If you measure how much you read vs. how much you would pay to read a comic one time, it's worth it if you casually read a lot. I think these services are generally worth it if you use them enough.
Comics are better read physically, anyway. Digital is acceptable, but comics are the one medium where physically holding it makes the most sense, because you can naturally, without clicking around, look closer at some panels, skip over the purposefully less detailed panels, etc.
