The CPU usage is unusual. I have pretty old mac (from 2011); have been running Tesseract quite fine. But, as to the accuracy, if your project is limited in scale, the commercial tools would definitely perform better for you. But, if you have long lasting, and extensive projects, Tesseract is worth spending your time and developing (training) it.
