T5HO Bulb talk

[LAX Noob Reef]

So I would like to know what you guys think of other T5HO bulb compare to ATI. I know ATI good all around, and stuff. What about the new brand GIESEMANN. Well, since it's only been out for few month; has any of you got these bulbs to test out? Also how is D-D Giesemann vs ATI, and KZ? I saw KZ brand a bit expensive.
