Personally, I prefer simplistic character sheets.
With comic reference sheets, there's a bit of leniency in the fact that its expected that models can shift and warp over time. I usually have a basic head turnout and a 3/4th back and front view of the main body. I also include a simple character bio and color swatches alongside it. It's enough for me to dissect the basic information, which I find to be the most efficient method.
The more rigid character sheets that have turn arounds from every angle are usually dedicated for animations. However, if you have an extremely detailed character with different items from every angle and/or feel the need to include more information for yourself, then by all means, make a more detailed character sheet!
Here's an example from my WIP comic for the Webtoons Short Story Contest:
Edit: For multiple characters, I recommend making a separate sheet that includes a front-facing lineup of each character so you can keep the heights in check. Use horizontal lines to indicate the inches/feet of each character. In my case, I only have two characters in my comic, so I didn't take that route. But for a more diverse cast, I'd certainly recommend it!
