Tesseract 4.0's accuracy is better than a tesseract 3. Tesseract 4 uses deep learning model: Long Short-Term Memory (LSTM) neural network which is a kind of Recurrent Neural Network (RNN).

But please check system requirements e.g. If you are using Ubuntu 16.04 LTS then Tesseract will be installed with version 3 and not 4. And if you are using Ubuntu 18.04 then you can install latest Tesseract version 4.

For more details please refer the following articles:
