Let me tell you i personally experienced both. I read Vinod Gupta and its very good book but at streach one can not complete all the modules. It contains 6 modules plus summary. If u taken depth knowledge from module than you can effectively complete summary in less than 2 days before exams. In case of Farooq sir, bcoz of his video learning and examples, one can get clear directions to solve the problems. So in my suggestion if u r good at DT and confident than go for V G and if u r quite poor than go for Farooq Sir.
All the Best !!!
