I personally prefer the Simply Lime packets. They do have a small bit of carbs due to actual lemon or lime peel grated a small bit of real sugar (1-3 grams per packet), but I don't exceed more than 1 a day normally, or a few on a really intense heat/sweat day in which ketoade is highly used.

Generally, me personally, I work to avoid dyes, specifically red dye #40 - as it is my gut's mortal enemy and the Artificial Sweeteners/additives: sucralose, Ace K, maltodextrin, dextrose, etc.

Generally, people will avoid sugar alcohols because their body reacts negatively to them. In my experience, most people have a negative intestine response....or as my family says "they give you the super poops. and not in a good way"

They are fine I've used them the whole time no issues. Also the Dasani versions as well.

I use PomBerry Mio and lime juice in my water for a 'treat', but prefer Nesfruta (made from real fruit juice concentrate.) It also has Acesulfame Potassium and Sucralose in it but has better flavour. Fave is Coconut Pineapple. I use less than a single serving in a 750 ml bottle because I just want a faint bit of something, not an actual juice drink. One container will last my husband and myself 3 weeks or so (I drink 2 bottles and he drinks 1 per day.) I've tried the stevia ones but they are too sweet to me, if they were more flavour and less sweetness I'd buy them instead.
