What type of teaching styles are better to pay attention to & what kind of slides are more interesting?

Teaching style is based on the student, experience level and information being taught. Use slides only as point of reference do not read off of them, very boring, involve your audience. Multiple teaching methods to choose from but as a tanker I would select the best method based on the subject matter.

Teaching styles are dependent on the student when it comes to effectiveness. Some are auditory and learn best through lecture. while others need pictures or getting hands on experience. Power point is great to get information out there, but to have the most effective training you need to incorporate physical, visual, lecture, and if available reference where they can read about the topic.

The majority of Marines and Soldiers I've come into contact with prefer hands on practical application and/or videos to death by PowerPoint. If you have to use PowerPoint slides try to incorporate some sense of humor provided its professional, or improvise to keep them awake and engaged. I don't care who you are, nobody likes listening to some guy drone on for hours.
