I rarely got any SR/SSR servants with a couple of x10 summon but I got 2 ★5 servants when I used the x1 summon using tickets couple of times so I was wondering if x1 summon is more likely to give you what you want. Or does it? I mean with 210SQ you can summon 70 servants in 70 turns but in x10 summon you only get 7 turns and it's likely to give you 7-9 ★3 servants/CE. So which should I use?
The statistics are the same no matter which one you choose. It comes down to your preference, seeing as you got luckier with single summons than with multi-summons. Multi-summon only guarantees at least one 4☆ card (servant or CE) and at least one 3☆ servant.
If it's like that then maybe you should stick with single summons for a while and see how your luck goes.
Multi gives a slightly higher chance for a 4* CE instead of a 3*. Watch FGO tips' overview of this on Youtube. The only benefit to singles over multi is a chance to save a few SQ (you can stop rolling immediately when you get the servant), but that is only if you get the servant, and only after spending many SQ will that be likely. But at that point, consider the opportunity cost of CE's. 4* can still be useful, especially during events.
conventional wisdom is to do a 10 roll if u are also aiming for some of the event CEs...and do single if u are just aiming for a servant. But at the end of the day, it boils down to your gacha luck.
