Ive used pempro, EQalign, Tpoint, WCS by Wolfgang Ruthner and helped Andreas set up Alignmaster for the Southern Hemisphere.
PhD2 knocks all of these into a cocked hat. I used it for the first time at Astrofest on the recommendation of a few people whose opinions I respect.
With no instructions, I was polar aligned in 10 min top and it stayed that way for the 10 days with perfect guiding. I wont be using anything else.
