Is Sudarshan Gujjar Sir really bad option

I Just purchased Unacedmy Plus subscription,and saw one of the post in this subreddit.Comments were very negative about Sudarshan Gujjar, infact whole Unacedmy tutors Pratik Nayak, Sidharth arora except Mrunal Patel.

I am a beginner and really don't know about teachers,that post put me in dilemma whether I did something wrong by buying Unacedmy.

Upsc veteran I need you suggestion 🙏🙏
