Light is light, so no, that fixture won't provide "better" light than any other fixture. The reflector in that fixture isn't typical for T5HO fixtures, so it will give less light than Tek or Catalina fixtures. 65 watt PC fixtures vary all over the map as to the quality of the reflectors, from fixtures with barely enough room for the bulbs, let alone reflectors, to fixtures with good reflectors. So, there really isn't any way I know of to compare those two options.
