It doesn't matter if you become lucid through WILD or DILD or any technique for that matter. All dreams have the potential to be extremely vivid and lucid just as much as the potential for them to be blurry and hard to control. Vividness and control comes with experience and skill at LD'ing, and both of those will take some time, so continue doing what you are doing. I have had extremely long WILD's one day, and a couple days after a very short WILD, so it always varies, but you get better the more you practice remaining in the dream staate.
