I've yet to read all that I picked up, and for the most part, these are new lines, or lines restarted, that I'm reading.
The ones I've finished so far are Supreme Power #1, 2; this line is a restart of a series of comic books that, IIRC, JMS started, and then passed on. Someone else has the helm now. When the line truncated previously, I wasn't too impressed with where the author of the time had taken it, but this set (of four books) looks like it might be worth sticking with.
I'll post about the others as I finish them.
