Low carb vs Paleo Chart Comparison

These charts look close. What do you see as the important differences?

Seems about right.
Low carb can have a lot of variation in carb and fat levels though. Most have carbs between <20g and 100-150g which can be higher and lower than 10%. The same goes for fat; most seem to have at between 50-75%. Protein is usually moderate but some go for lower or high.

For sugars and wheat, you may want to change it to trace/very small instead of no. Most eat some of those products like in a gravy or sugar alcohol in a treat. Most low carbers have some, just not much.

For wheat, ... I would consider adding grains. Many low carbers use some grains. Wheat is just one type of grain. For flours, if we bake coconut or almond flour is generally used.

Legumes - does paleo allow legumes? Small amounts or trace legumes are common in a low carb diets. For example, I had a spoonful of refried beans in my taco salad yesterday (pork, chicken, cheese, sour cream, avocado, and lettuce).

The two types of diets are often complimentary. Low carb is mainly focused on macros of fats and carbs, but within that there are many woes to achieve that: vegetarian, vegan, paleo, primal, carnivorous, moderation style,IIFYM, "clean eating" or others.

20% carbs isn't overly low, and if it were <50g the fat would be way higher. Stevia is OK on low carb, as are aspartame or sucralose. They aren't sugar though so perhaps stevia shouldn't be in the paleo column.
