It will really depend on what you like best and the bulb you are using. The giesmann actinic + is a very blue bulb and bright, makes the colors really come out. The actinic from ATI (make sure its really an ATI bulb) is more purplish but it too makes colors really stand out. I liked running a combination of the ati actinic, the giesmann actinic plus then a 6500 k GE bulb for par, it was a more yellow looking bulb but the actinics usually washed out most of the yellow look.
