"fake" nails have come a long way.
The OP asked about Gels which are IMO a vast improvement over acrylic and not even comparable. A true gel has the consistency of thick syrup - it is applied, allowed to settle and cured under a uv lamp. The "burning" sensation varies person to person, lamp to lamp and it is caused by the heat generated by the chemical reaction of the product setting.
Many salons use acrylic (liquid & powder combo) and then put a thin gel layer on top and sell it as a gel nail. This method is not a true gel nail.
I have been wearing true gel nails for 2 years. In that 2 years I have not had a single one break. They do not lift, they are always shiny and I get them filled every 3 weeks. They are thin and lite weight. I prefer the pink and white french in a sport length (pretty short). For special events I will do a colored/glitter tip. I have also had gel toes done. I pay $35 for a fill with tip. Everyone I know has nails of some sort. The short/french is really popular.
The product stays shiny, does not get "sticky" when using sunscreen like so many nail products do and for me does not break.
