I think this is great advice, since the first few years of my tax career were spent helping people deal with all the crap that CPAs got them into.

CPAs are good at math and accounting and generally quite bad at reading and applying the law. Use a CPA for your tax filings, and use a tax lawyer for anything that involves complexity. Tax law is administrative law, so a lot of things that would apply to criminal law doesn't apply (for example, tax strategies can retroactively be deemed illegal, taxpayers can be penalized for violating the spirit of the rules despite adhering to the text of the rules, etc.).
