Say I want to talk about my own ability in some area of expertise or at some activity. What would be the appropriate word choice? Assuming a casual to polite context.
Would 「できる」 sound pretentious?
What about trying to express that one is "okay at" something (not good, but not bad either)?
What about other degrees of ability (terrible, bad, "can do a bit", passable)?
To give a concrete example of what kind of sentence I'm thinking of:
I'm quite good at reading, but I'm not good at writing.
