It is true that some courses on Lichess may be more helpful than those on Chess.com. Lichess offers many courses created by users, and they can be a great resource for learning and improving. However, Chess.com also offers many courses and resources that can be helpful for learning and improving at chess. For example, Chess.com has an extensive library of video lessons and articles, as well as puzzles, quizzes, and other practice materials. Additionally, Chess.com offers premium memberships which provide access to additional resources such as live lessons from grandmasters, interactive game analysis, and more. Ultimately, it is up to you to decide which platform suits your learning style best.
Yes I agree with you its ultimately the choice of the player what they prefer.
Personally, I feel like there are the courses for studying on LICHESS (if you find the right one) are more helpful than that on Chess.com. I'll have you take into consideration that while most of the courses on Lichess are created by users for users and may contain some errors undoubtedly the courses on Chess.com just don't feel friendly enough. For example, my friend was trying to learn the Dutch Defense finished the lesson on Chess.com, watched some Youtube videos, and got some books but was still falling behind after a lone course on Lichess got into shape. I believe you understand what I am trying to say. Those of you who use both definitely see where Chess.com leaves Lichess in the dust but then again paid vs free isntisn't fair now is it?
