Perhaps, but I'd still consider them better than white sugar.
Edit: I love how you can’t ask a genuine health question here without being down voted. The sugar industry has spent decades brainwashing people and using fake science to push sugar. Even recently I thought there were a lot of concerns over sweeteners hence why I asked the question hoping to gain some insight as why that is not the case. I have always thought sweeteners were worse in many ways but I don’t have any thing backing that up. I was genuinely asking because I am now wondering if I have it wrong about sweeteners. Thank you to those who added some insight.
The common artificial sweeteners are generally considered safe for consumption, and moderate use instead of added sugar can help achieve a healthy weight to reduce the risk of heart disease and diabetes, as well as better dental health.
Artificial sweeteners have been studied for decades, and there is no sound evidence they are carcinogenic. There are some other potential negative effects on health though, which are being studied. One concerning correlation is that people who consume diet soda regularly are more likely to be overweight. These articles provide a good overview:

Unless you're diabetic or have diabetes markers you really don't have to worry at all about glycemic index so at that point sugars aren't inherently bad, it's just their ubiquity as a favour enhancer
