These banners are best for 3* story limited rolls. Normal rates for "rate up" 3* is fucking garbage at 4%. You don't notice this much of the time because you can just get  most3* from Friend Point summons. However, during a class based summoning the chances typically improve overall. You have a 10% chance of getting Bedi (40% (chance to get a 3*)/4(number of Saber 3*) = 10% overall). A 5.7% chance of getting Taiga (40%/7(number of Lancer 3*) = 5.7%). The chance of getting Columbus or Red Hare is 6.67% individually (40%/6(you should understand what this number is by now) = 6.67%). The chance of getting Caster Cu or Caster Gil is 5% individually (40%/8 = 5%). The kicker is the EXTRA banner. Since Salirei is the only EXTRA 3* you have a 40% chance of getting him every pull. (40%/1 = 40%).

Salirei benefits from this banner the most but overall this is going to be your best chance at getting most story-locked servants in the 3* range so it's up to you really. Do remember you're guaranteed to get at least one 3* or better on each 10 pull, so that means you are near 100% guaranteed at least one Salirei every 10 pull. (And if you don't get him you're getting a 4* or 5* instead.)
