Well, of course the answer is "it depends on what it is you want to learn from the map. If you're driving around and want to navigate, you'll take Mercator probably. But if you want to compare sizes of objects (like lakes or forests or islands or world states), especially when zoomed out, you'll prefer Gall-Peters.

Many argue, and I tend to agree, that when looking at a map of the whole world, you are typically better served with Gall-Peters in terms of what your interest is, and in fact, people _do_ use Mercator maps to semi-consciously compare sizes of things - and have false impressions about geo-politics because of it.

You've been repeating essentially the same comment, writing in all caps (in some comments), complaining about downvotes, telling everyone they are idiots one way or another. None of those things are likely to be welcome.
