> Tesseract (which is the best I have so far)

Have you looked at EasyOCR?

EasyOCR is significantly worse than Tesseract for clean printed text and , while being orders of magnitude slower; far better than Tesseract for low-quality clean scans and extracting text from pictures (e.g. comics), which Tesseract does not as well.

Have you tried Abbyy FineReader? It's the best OCR package I've seen.

It doesn't seem to have a Linux version; I don't have a mac or windows machine.
