I use partial mostly... Though the fact manufacturers they include all the other options shows the need for them in special circumstances. The one I have least success with is evaluative, perhaps because it makes the decisions and so is least controllable.
When I used a hand meter I mostly used incident light, as it pegs the highlights and works what ever the background colour or situation.
The histogram is very useful, especially if you remember it basically counts how many pixels there are at each value and displays them as a graph. E.g. a dark subject should have most pixels showing on the left of the graph, so mostly, it is not helpful to change the exposure to move them to the right.
