Top tablets 2014, the best tablets 2014

What is the best tablet for today in 2014? I am planning to buy a tablet for my final year project related activities. Tablet is required to test some Cloud Computing application functionality.

Please suggest some quality tablets I can buy. I already have a Dell laptop and a desktop computer in my project team. We also have android smartphones. Before tablet purchase, we would like to ask experienced people.

We went to a nearby tablet shop and reviewed Samsung and Karbonn tablets, sales executives say both are of very good quality. But we wanted tablet which can perform well and having long battery life when using on Wi-Fi networks.
My recommendation is to go for a Karbonn tablet is you are buying it for your collegege project. I have been using Karbonn tablets for more than and year now without ANY problem, it cheap (INR 8000) and performance is very good.
