Better for what? The best language is simply whichever language works for you and let's you get the things done. Common Lisp is certainly more mature than Racket, but Racket's language design is cleaner and has widespread community support. However, Racket lacks certain features such polymorphism. Try both languages, that's the only way to really determine which is better. That is; which is best for you, personally.

Some popular Common Lisp books include "Practical Common Lisp" by Peter Seibel, "On Lisp" by Paul Graham, and "Common Lisp: A Gentle Introduction to Symbolic Computation" by David S. Touretzky. These books are well-regarded for their coverage of Common Lisp fundamentals and practical examples. Ultimately, the best book for you will depend on your learning style and goals.

Incorrect placement or number of parentheses will probably make the most common syntax error in LISP programs.
Changing a racket takes a few weeks to get used to. If you like your racket and you feel comfortable playing with it, then I consider just changing the strings. If you don't feel comfortable with your racket and you feel that you can do better with another one then just get a new racket altogether. It really just depends on your racket and if it feels comfortable to use.
The word "lisp" is spelled L-I-S-P.
