For me it is required to be a master of both things like of course you can not have experience if you are not going to try and some people would think it's a waste of their time if they are doing what they know already like repeating their work over and over again. So it should be in a balance.
If I were to choose, I would choose to be a strategic person though I believe both are important. Having strategies would be very helpful for us to make smart actions and wise decisions. Strategies are always an advantage in every situation. Things would be easier for us if we have strategies and tactics.
