Felt like giving attention to the later runs since I don't hear them talked about as often. Claremont left after #279 (and returned in 2000 and 2004) and I know there were more writers that worked on the title than the ones I'm about to list, but as a general idea:
Whilce Portacio (1991-1992, #280s)
Scott Lobdell (1992-1997, #280s-340s)
Steven Seagle (1997-1999, #350s-360s)
Alan Davis (1999-2000, #360s-380s)
Chris Claremont (2000-2001, #380s)
Joe Casey (2001-2002, #390s-400s)
Chuck Austen (2002-2004, #410s-440s)
Chris Claremont (2004-2006, #440s-470s)
Ed Brubaker (2006-2008, #470s-500s)
Matt Fraction (2008-2011, #500s-530s)
Kieron Gillen (2011, #530s-540s)
