I haven’t seen anyone else mention this tool yet, but I’ve found great accuracy and flexibility with [OCRmyPDF](https://github.com/ocrmypdf/OCRmyPDF). It (usually) detects and fixes page rotation, and works quite well on slanted text or A | B pages in regards to copying and formatting. I believe it uses tesseract in the background, but using it is very simple and it has the just works factor.
