Congrats sathi! I would go the DV route if your rank is low. I guess less than 15 - 20,000. Even if it isn't, since EB3 takes some time anyway, isn't it possible to try both? Let the recruiting and stuff happen for EB3 and move ahead with DV. You should find out about DV sooner and can withdraw EB3 if needed. Consult a lawyer though.

With EB3, there's a chance you might get audited which can extend the process. Also if some US candidate applies for your position and meets the requirements, your EB3 process has to be restarted. My suggestion would be to go simultaneously if you are in the early phase of EB3. Consult a lawyer sathi. Good luck and congrats again!
