I really like it when I solve any Machine learning problem, It has a lot of inbuilt ML models that are tough to implement but here those are easy to use.

It is very useful in the beginning for data mining and data analysis. Easy to use. It provides maximum efficiency with minimum effort. Data processing, regression, dimension reduction, classification, cluster analysis are the features I use. It's completely free.

The best thing, as per me, is there is documentation available of scikit-learn. So, if I sometimes find it difficult to apply some algorithms, I can check the documentation, which helps me. I like this thing. Scikit-learn also provides many inbuilt datasets so that I can use them for practice purposes. Scikit-learn comes with many machine learning algorithm, which makes easy to me for implementing algorithms. I like that it comes with many data manipulation functions to clean my data according to my requirements.
