Either and any will be fine as a beginner.
Nothing will teach you more about a spot meter, or your own strengths and failings with one, than getting your hands on one and actively using it in situations to build up a skill foundation. Spot meters have few cons as opposed to many pros: they are very, very accurate when used competently and the results are understood and you know when to apply judgement. True, they take a bit more time to scoot around the scene evaluating luminance, highlights, shadow and mid-tones — the locations of which have to be ascertained by you. It is very stimulating and perhaps even addictive. Practice makes perfect, but maybe don't expect fantastic results on your first outing with one, but over time the results will speak for themselves based on active experience.
