We’ve only used the Norwex brand of laundry sheets. We loved them but they were pricey. No trouble with them dissolving, even in cold water. No scent.
When we came to the end of our sample pack, we decided to try a recipe we found on Pinterest. It uses basic, inexpensive ingredients, has only the scent we add (lavender essential oil), is easy to make, dissolves in any water temperature, and gets our clothes clean. I don’t think we will ever buy commercial laundry detergent again, unless the sheets come way down in price and we can verify that the ingredients are not harmful.

BTW, I’m not sure everyone understands that liquid detergent, including pods, is mostly water. That means we are creating these huge plastic containers, freighting them across the ocean and the country with all the related pollution, lugging them back and forth, storing them, and then throwing those plastic containers into the landfill, all for water. Sheets contain no water, weigh nearly nothing, can be stored in recyclable paper/cardboard boxes, and take up nearly no space. Environmentally I can’t think of a better solution.
The recipe I’ve linked above uses 3 dry ingredients which are purchased in cardboard boxes or paper wrap. I believe that is also a good environmental solution.
