You simply can not rate any course as best, until you can not experience any of the course from them, but from my experience, I am telling you from my experience because 1 year ago when I started learning Tableau I did a decent research for the best place I took some of the courses and then I finally found, Intellipaat who is the best online training website for Tableau in PAN India. Remember this is my choice but, I can confidentially say that you will also like their course.
Some of the benefits which you can avail at Intellipaat are lifetime course access with lifetime support, and also whenever the course will be upgraded you will get the free access and this is really helpful.
Other than this you will get to learn from the trainer who is having 10+ years of industrial experience in the particular technology. Isn’t it cool that you are knowing all the industry trends before stepping inside it?
If you want to learn Tableau then must have a look at the following Tableau Training Course. You can also watch the below-mentioned video tutorial on the Tableau to learn more about it.
