The splitter will do the job if you are doing a short run, but remember that any time you split a signal of any type, you are cutting the strength of that signal in half. As HDMI generally only has a maximum transmission distance of approximately 50 feet anyway, using a hdmi cable splitter would only really be relevent in very short splits. If you are concerned about quality, which i am guessing most of the people on this forum are, you would want to go with the switch, as it is active and it amplifies the signal as it splits it, which will cause a lot less problems when doing longer HDMI runs.
