Let's analyze properly:
 * +30 ability power = +18 damage on his E.
 * +30 attack damage, which factors into his Q and R, and thanks to his crit chance is practically worth double on autoattacks.
 * +30% attack speed, which lowers the cooldown and cast time on his Q by along with increasing his attack speed.
 * +10% crit chance, which translates on him to 20% crit chance.
 * +250 health, giving Yasuo a bit of defense.
 * +200 mana, which is arguably the only useless stat on this item for him.
 * +8% movement speed, allowing him to stick to enemies better and charge his shield faster.
 * +The Rage passive, which gives him even more sticking power and shield charging speed.
 * +The Spellblade passive, which Yasuo can activate every 2 seconds and apply with his Q for 215.2 damage a pop at level 18.

All this for 10% less attack speed and 10% less crit chance than. If you can afford Trinity Force, take it. SS is the real noob trap here: only buy it if you're not doing well and need to fill up quickly on offensive items, otherwise pick TF.
