You should grail only the servants you like the most, really. If you are, however, looking for usefulness, it's better to grail the 3 star and 4 star servants over the 5 stars, since they'll get 5 levels instead of just 2, and that gives you more servants on the level of 4 and 5 stars with less grails than a single 5 star servant getting maxed to lvl 100. What people usually do is max their waifus or husbandos, or, if you manage to get her, the most OP servant of all, JAlter, however, with mooncancer now being a thing, I don't know about doing that anymore unless she's your waifu...
