Inground vinyl is better, their is less exposed part to the oxigene, therefore, last longer.
An inground pool is typically lined with either gunite (concrete), fiberglass, or vinyl. Gunite and fiberglass are roughly the same cost, whereas vinyl is considerably cheaper. With the lower price comes less durability, as vinyl lining has to be replaced every 8-10 years or so, whereas the other two can last for decades. Vinyl is also much easier to puncture or otherwise damage. That said, many people still prefer vinyl inground pools due to the lower cost.
Well first of all there is no such thing as a fiberglass pool. You can have fiberglass walls instead of steel but your pool is still vinyl because you need a liner. These are the usual combinations of inground pools.

In South Alabama the cost of a 20 *40 vinyl pool will cost around 18 to 22 thousand
There are three main types of inground swimming pools: concrete, vinyl and fiberglass. All of which are prone to the occasional crack. Luckily for the homeowner such cracks can be repaired. If you are handy you can purchase a do it yourself repair kit at your local pool specialty store.
Don't do it. Too many possibilities for leaks. Get Fiberglass or vinyl pool, learn to install that instead.
Fiberglass pool shells are shipped in a single piece directly from the manufacturer. As a result, you don't actually linea pool with fiberglass the way you would with concrete or vinyl. Instead, installing a fiberglass pool simply means digging a hole in which to place the already completed shell.
Inground concrete or fiberglass are the easiest pools to maintain. When you get into synthetic materials like vinyl and plastic, it's harder to find chemicals that will do the work without damaging the pool.

you will find that people will swear by either method and then others will say in ground gunite or concrete is best . If properly maintained they are all much of a muchness. from what I have seen When they are new the vinyl pool looks better. the problem is that the vinyl will need to be replaced eventualy while you wont have this problem with fiberglass.
