From a practical viewpoint, the incremental benefits of grailing a 5-star servant is much lower than that for other servants. Hence, I don't grail 5-star servants, as I will only get to enjoy a 2-level increase in statistics. Instead, I focus on other servants who benefit more. I like to grail some good 4-star servants so that they are more comparable to 5-stars. Or some 3-star servants to boost difficult fights where your cost is high (from some 5-star servants and CEs), and need to rely on some lower cost servants.

Another point to consider is how much the stats improve after that. Some servants' stats grow even faster after their maximum levels (e.g. Lancelot) while others slow down after that (e.g. Heracles).

However, as what many people say - it is perfectly all right to grail whoever you like. It is more like a bonus - you don't necessarily need to rely on grailing to excel in the game. Those that I have grailed are: Lancelot, Heracles, Frankenstein, Chloe, Saint Martha (swimwear), Cu Chulainn, Euryale.
