Trained data from tesseract 5 are compatible with 4, so definitely I would suggest using the latest tesseract version for training - there was a lot of bug fixing and speed improvements.
IMO tesseract training has never been easy. I always suggest focusing on image preprocessing rather than training. Following an easy looking training tutorial could also mean you are on the wrong path (=> you waste your time and it increases your frustration). For example:Tesseract 4 has 2 engines LSTM and legacy engine. In this particular video, for which engine is that training? For hints see[1]. Did you plan to train that engine or other one?
