All depends on what you are looking for and how much you have to spend. Concrete pools are usually considered the "high-end" pool but installation takes a long time and maintenance and repair are costly. Steel pools, or I'm assuming you're referring the vinyl liner pools, are a good, cost efficient option. Though, if you want to extend the life span of your pool, check out the other building materials used for vinyl liner pools.. such as Fiber Reinforced Composite Materials.
In above ground models, wood is much better than steel. If you "rough house" in a steel pool, you potentially could knock it down. It you run into it with a bike or lawn tractor you will likely know it down. A wood pool you could back your car into and not know it down. Wood you probably need to treat every 3 years, steel you don't, but it will rust. I don't have info on concrete.
No, because fiberglass can make you slip unlike concrete steps
because concrete is unpredictable than steel

Concrete is unpredictable compared to steel...
All day long. Concrete pools have real tile instead of the fake liner tile look. You can update a concrete pool later on as styles change: with vinyl it's final.
steel
Steel is generally stronger than concrete in construction materials. Steel has a higher tensile strength, meaning it can withstand more tension or stretching forces, while concrete is better at withstanding compression forces. This is why steel is often used for structural elements that need to support heavy loads or resist bending, while concrete is used for foundations and compression elements.
Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.
The Berlin Wall was more than steel and concrete. What did its construction AND destruction symbolize?
Composite pool walls for vinyl liner pools are better in that they are 100% non-corrosive while still supplying the same amount of strength as a steel wall pool. While nature ensures that steel WILL rust over a period of time, the increasingly popular salt generators have accelerated this process. And why is rusting panels bad? Think of your vinyl liner moving up and down on a rusted piece of steel.
No, steel is denser than concrete, so it is heavier by volume. However, concrete can still be heavier in certain applications due to its bulkiness and ability to be molded into large shapes.
