Most people are best served by the big vendor OCRs. In my experience Amazon’s works the best, followed closely by Microsoft and Google at a distant third.
Agree it’s best to skip tesseract unless the free cost is important. We spent a lot of time trying to preprocess and tune tesseract before realizing cloud OCR solutions are much better and fairly cheap.
I haven't seen it make any mistakes at all and responses take less than 3 seconds usually.
