My wife and I are beginner snorkelers and had a great timer at Malmok. We stayed close to shore and saw incredible numbers and diversity of fish. I would rank this site higher than Baby Beach but definitely lower than Boca Catalina and Catalina Cove. Be very cautious with your belongings here and elsewhere on the island. Don't leave anything in your car or any valuables on the beach/rocks. When we checked out the Malmok entry site, we left an inexpensive digital camera in the rental car for 10 minutes. When we returned the window was smashed and the camera gone. Don't get lazy and let your guard down like I did.
