nothing wrong, with a web crawler project you will sharpen your algorithmics thinking and when you dive deeper you might learn how internet/http/web works, control flow with concurrency/parallelism, and many more. its always better in programming if you have/know- reason for using tools/library when you decided to use it, because thats a signal that you know what you're doing.
so, which library is the best? it depends on problem you want to solve
