Does ultra light cigarettes stain teeth less then stronger ones, what about type of tobacco and additives in tobacco?

Awkward...: This is like asking a professional driver if they prefer to drive on nails or large staples. No dentist should tell you that cigarettes will not harm you or that additives are going to make a big difference compared to smoking vs not-smoking. Staining won't matter as much as serious health risks. So: if you like smoking that much, pick your favorite product... But really think about quitting ;-).

Not really : Nicotine is what stains the teeth. Studies show that ultra light smokers actually smoke more cigarettes so the teeth receive just as much nicotine. A dental hygienist can remove some stains but over time the nicotine makes it's way into the grooves of the tooth and is hard to remove. This can be worse with smokeless tobacco due to the juices. It's best for your teeth and health to stop smoking.
