UH I've spent a lot time in unit 1 in AZ and there are a lot of big bulls in there. Unit 1 would be my top choice for AZ with Unit 9 a close second. Unit 1 just has a lot of elk and trophy size bulls. The terrain is good with open areas, high spots for glassing, access to areas and camping. Unit 9 has good trophy potential, but is much thicker and harder to glass. Most of the unit is public land and has elk throughout which disperses the hunters fairly well. I've hunted elk in AZ for 20 years and Unit 1 would be my top choice, next to the White Mountain Apache res, which isn't affordable. Go for it and good luck! It should be the right year for regrowth, big elk and usually best time is end of Sept & 1st week of Oct.
