When it comes to being inscrutable, how much is too much?
Can one be more inscrutable? Would that then be being inscrutabeler?
Is it better to be scrutable?
Yes, of course it's better to be plain spoken.
Well, at the risk of being pedantic, the word scrutable is not actually the antithesis of the word inscrutable.
While inscrutable means "difficult to understand", scrutable doesn't mean "easy to understand" or plain spoken. It means something that
can be understood through careful scrutiny, or something that is open to scrutiny.
If you are going to "baffle them with" $10 words, you'll get extra points for using them correctly.
