Well let's break down stuff.

I see 3 ways to naturally sugar stuff that are decently common.

Firstly let's talk about white sugar. It's refined, almost entirely composed of well... Sugar. Pretty nice when you want an energy boost but unless you are moving around and not consuming it in vast quantities, you're fine.

Secondly brown sugar. Contrary to popular belief, brown sugar isn't way better. It just contains molasses that while sugar has been deprived of through being refined. Those molasses contains trace amounts of calcium, potassium, iron and magnesium but I think you'd be better off eating a banana if you want minerals.

Thirdly there is honey. Honey tastes sweeter but only because the molecules of fructose taste sweeter than regular sugar. In counterpart for the same weight of honey you will have more calories than with sugar. Though if you took the same amount of calories in white sugar or in honey, honey would be more healthy because it's molecules are generally more healthy.

There are other forms of sugar like palm sugar and coconut sugar but I am not an expert on those. I believe they contain mostly sugar but I don't know about their calories content or real health benefits.

Now let's see about the artificial sweeteners. Artificial means obviously chemicals. Aspartame for example is composed at 50% of phenylalanine which is... drum rolls a powerful neurotoxin if you ingest too much of the stuff. Stuff like agave nectar have been linked to reducing your metabolism which makes you burn less calories, therefore gain weight for the same diet and activities as well as reduce your insulin sensitivity. There are also sugar alcohols that seems nice to use because only about half gets digested but too much of it will give you diarrhea.

There are other and I don't wish to spend an hour listing them and telling how bad they are. Generally the more you pay for it, the healthier it gets because who would sell cheap healthy chemical stuff. Most things I read on artificial sweeteners is that it was approved but didn't get "enough" testing.

tl;dr: Any sugar is safe as you don't consume a shitton of it. Almost any artificial sweetener is fine as long as you don't consume a shitton of it. So unless you have 0 will power, diabetes or are overweight, I would stick to sugar or honey in moderate quantities.
