The big four will always be Ron Smith, Brian Bolland, Mick McMahon and Carlos Ezquerra. Not necessarily in that order. They defined Dredd.
I agree with that. My order would be Bolland first...then dunno lets call it a draw.
I'd give the next place to Ian Gibson, especially his work in the early progs.
I would put Gibson in a group with Brett Ewins*, Brendan McCarthy, Cam Kennedy, Steve Dillon, Cliff Robinson and John Higgins as "classic
" Dredd artists after the big 4.
And I view that there is a modern "holy trinity" of Henry Flint, Colin MacNeil** and Ben Wilsher.
And of course, sitting proudly along side the modern holy trinity, as a guiding father figure if you like, we have....yeah you guessed it ....Carlos Ezquerra.*And yes Brett actually drew very few episodes of Dredd and is probably better know for Anderson, but the stuff he did on the Day the Law Died with Brendan is just awesome (even though I can't tell which bits were Brett and which were Brendan
)**And yes #2 MacNeil has been around since the late 80's but he seems to draw loads of Dredd episodes these days
