Really I'm wondering if an entire army can win best painted, and your attempting to talk about individual models. It's apples and oranges.
Marines can win best painted army, they just have to go the extra mile to make sure everything is clean and theres a noticeable amount of freehand work. Honestly they aren't the hardest army to win it with, tyranids are very difficult to make look interesting (everyone looks the same), as are the necrons (everyone looks the same and silver).
it's much harder to do Tyranids or Aspect Warriors or even Guardsmen well
Not really, 2 stage drybrush and light highlighting then minor detail work makes a tyranid look great. All those little crevices and details take to drybrushing or inking very well, and the models are basically just three tone carbon copies of one another. As for aspect warriors, those have the same problems as marines, large empty curved surfaces and plate armor.
