Judd winick and Kevin Smith are part of the same volume IIRC...that ran from 2001 to 2007.Would you suggest to read them in that order, or read them in any order?
Kevin Smith was on the first year, then Brad Meltzer, Then Winnick.
Jeff Lemire was the second writer on the new 52 reboot, so his mythology is new and there's no real need to read anything before it.
He also ignores the first 16 isdsues.

Green Arrow Vol 5 17
"The Kill Machine, Part 1": Oliver Queen has lost everything. He woke three weeks ago to discover via the newspaper that Queen Industries was sold to Stellmoor International by Walter Emerson. When he confronted his father's old Green Arrow (Volume 5) #17 is an issue of the series Green Arrow...
other worhthwhile modern runs:
The current volume (By Joshua Williamson and now Dan Watters) is also pretty cool.
The rebirth run by Ben Percy is pretty cool, a bit of a knockoff of Lemire's run.
The only two runs you should avoid are:
2007-2011 comics
New 52 issues (2011-2016) not written by Lemire.
Green Arrow also has classic runs in the 70's and 80's..I just gave you the modern ones.
