Some people just hate keeping the mic just in front of their faces, but it's often the only reasonable way to achieve tolerable signal-to-noise ratio (in noisy or/and reverberant environments).
You need to decide where are you going to use the mic, how are you going to place yourself and the mic in the room, how free in your movements do you need to be while recording, and then choose the type of the mic accordingly. After that, the budget is often the deciding factor so you can seriously narrow down the options.
Anyway, I also highly advice using separate vocal/podcasting microphone (the kind you buy at music stores) and the headphones of you choice over headsets or, god forbid, internal laptop mics.
