I think among the easy-to-use FOSS CLI tools, the competition is between Tesseract and PaddlePaddle. I'm interested to know how they fare against each other. I'm mainly interested in using them in `ocrmypdf`
If you prefer not to install it at this stage, there is a chance that PaddlePaddle has a web interface - maybe you could try and see the results against a document also processed with Tesseract (also those in the article, if the scans are available).
