My country has had 2 women presidents. Their record is mixed, depending on who you talk to but you could say the same for men. If you look at it, given how messed up the world has been in the past and the present, it's hard to say that men have been doing a good job.
Going to the question, I would say yes. I would vote for a woman president. In my opinion, they are just as capable as men to serve as heads of governments.
At the moment, two of the major economies in South America, Brazil and Argentina, currently have women presidents. The former president of Chile, the one preceding the current president, is a woman. Islamic countries such as Turkey, Pakistan and Indonesia have had women leaders.
In fact, a number of countries from both developed and developing economies have had women heads of State/Government.
