It's about the same. Nitro will just perform a little better. No spring to wear out. The Nitro piston guns have a sealed strut in place of a spring, there's no maintenance required.
The Nitro piston is superior to the spring piston in design, but Yes, it can be converted back to a spring in most cases. It is best to have it done by an "air gun smith."
When you cock the rifle it compresses the gas behind a piston just like a spring. Basically it replaces the spring.
The nitro piston replaces the spring piston. It's simply gas that is compressed inside a cylinder instead of a spring. You can compress gas. So each time you compress the nitro it acts like a compressed spring. you don't have to add more nitro each time you shoot it stays in the cylinder. Gas is more even as it expands so you get a steady thrust when the rifle is fired. A spring uncoils, giving an uneven thrust as it is released.
Yes there are some newer spring air rifles that are capable of being switched to Nitro Piston Gas systems. Check with the manufacture.
Yes it is an excellent design.
Because of the small design of a BB gun it is not possible to change the air system. However if it's a pellet springer rifle, not a BB rifle, then in some cases it is possible to change it with a Nitro piston system. But this should be done by a professional air gun service. A nitro system replaces the spring piston with a gas piston tube. It usually cost around $130.
Actually air guns have very little kick. Nitro is about the same as spring. Nitro has the advantage over spring in that it has no "spring wobble" when fired and it can be left "cocked" for a long period of time without damage to the system.Actually air guns have very little kick.

This question sounds more like a statement than a question. To try to answer you, you have to understand that Nitro is a fairly new product, it's going to take time to find out which will last longer. It's too soon to tell.
Nitro
electric has better performance and is cleaner but nitro can fly for ever if you have enough fuel
Gamo makes a dozen different rifles and pistol's. I find then to be of Very Good quality. I personally prefer the Nitro piston models over Spring. The new Dynamax (PCP) looks promising but expensive.
