It depends on what you get out of spending 600 euros for the new tablet. It may be a little faster or have more memory, but at a certain point, that speed won't make a noticeable difference with MobileSheetsPro (but it could if you utilize other apps that do serious processing). The battery would be brand new, so that's certainly a benefit depending on how much the battery had degraded in the Tab S4. If the screen on the new tablet is the same size as the S4, I think I would personally go for the 300 euro repair unless there is something else you would get out of switch to the 600 euro tablet.
