The best part is that it has all the tools to build an NLP model for any task you can think of! It's easy to use and comes with great documentation. I dislike how slow their website loads sometimes. Other than that everything works perfectly fine and there are no downsides at this point. We have been using NLTK for years but we were not able to get as much out of it compared to what we could do with Gensim. Thanks to HuggingFace our team was able to solve problems they didn't even know existed before using these libraries.
