You pick Kassadin as a counter-pick against most AP mages and some AP assassins, since his passive and magic damage shield, not to mention his mobility make it difficult to kill him im lane. You also pick him as a lategame insurance policy for teamfights since at 4 items to full build you will assassinate the enemy targets regardless of BTs or QSS or Hourglass since again, his burst combo isnt tied to an amplifcation\debuff spell that can be cleansed or negated.

Fizz on the other hand works as a more conventional 100-0 assassin, that spikes faster and harder at the 1-2 item breakpoint due to his ability to tag people with an ultimate that works as both a lockdown spell (lets face that slow into knockup combo is monstrous) and damage amplifier, so in a sense until the enemy team stacks QSS and Hourglass his single-target burst combo is near-certain. Also his W works as a mini-Ignite which will once again again act as a kill secure mechanism. You pick him as a means to reach and explode the backline at the midgame stages before the enemy tesm can react.

It pretty much boils down to what game phase you are playing for and what kind of team comp you are facing. Are you facing an AP heavy comp? Maybe facing a comp with alot of peel\cleanses\shields? Take Kassadin since his ability to engage, dissengage and re-engage teamfights will eventually burn through those protections.

Dealing with a more carry-based comp with not alot of tanks or peel support? Maybe a double ADC comp or a global pick comp with TF? Or going against another assassin like Zed or LeBlanc? Are you playing to end the game pre 35 min? Take Fizz since he can either them in lane post 6 with ease or mirror the enemy roam and go for a revenge kill\counter-gank.
