Strings for tennis and racquetball are a lot like rubber bands. At impact they give, stretching out, then snapping back, returning the energy to the ball. The more a string can be made to give at impact, the more energy goes into the ball for more power.
Softer, multifilament strings are more elastic and will give more. For players who want more power and depth on their shots, these strings are a great option. In addition to the added power, they also absorb more of the impact, making them easier on the arm.
Poly strings are less elastic, and therefore have less power for most players, For the really big hitters who can make poly strings give enough, the power can be great. 
The other thing strings have in common with rubber bands is that over time, they lose the ability to "snap back". After a while, a rubber band left stretched out will not snap back. Tennis strings are the same. After some time, they will not return as much energy to the ball, causing a loss of power and depth on your shots. For harder hitters, this will happen quicker, but eventually, this will happen with all strings. A good rule of thumb is to restring after a six months to a year if the strings have not broken, as they will have lost a good deal of the "snap back" and the performance will have dropped.

Racquetball Rackets and Fan Patterns

Racquetball rackets have come a long way. They are more powerful than ever. The additional power comes from better materials making the frames stiffer and new, more open, fan string patterns.
Those string patterns "fan out" as you go up the face of the racket, creating more space between the strings. This increases the give in the strings at impact, returning more energy to the ball, and more power.

Power is great, but there is a downside. Durability.
All that extra give in the strings puts more stress on the strings and for hard hitters, can cause more frequent string breakage.
If you are a really hard hitter and the softer strings are breaking to quick, switching to a tougher, nylon string can add string life without giving up much power. There is a trade-off. What adds durability takes away power and vice-versa. Every player has to make a decision on which is more important, knowing the pros and cons of each string.
