Like you, I have enjoyed everything I have read. There is the odd Dredd tale I groan at when reading the case files but overall they are exceptional.
Like Colin suggests, its all so subjective and up to personal tastes. For example, Rogue Trooper is one of my favorite strips! However, Leviathan, although the favorite of so many people, wasn't my cup of tea. I recently purchased and read ABC Warriors and loved the Meknificent Seven but didn't really like black hole.
It all comes down to preference, so read it all and then decide!
