Depends and match up.

Arcane Comet is almost guaranteed to hit, since roots the enemy and  slows, that means it's easier to trigger and will therefore proc way more often. It also is AoE, so it can hit multiple people if they are grouped.

Electrocute is a lot more tricky to proc, as it needs 3 seperate instances. And your passive does not count as an additional one, so a quick + AA (+  won't proc it. That means it's way harder to actually trigger it during lane, at least against ranged opponents. However, the sheer damage is superrior to Arcane Comet and thus adding to your combo burst. It also is only single target.

The question what of them is better comes down to the question wether you want raw burst or poke. Electrocute will add to your burst damage, making your combo a lot more deadly. But you will have weaker trades in lane and your poke will be mediocre. Comet will instead add to your poke and grant you better trades during laning phase.

Now the match up question:

Purely on lane Comet is better than Electrocute in almost any match up that is ranged. In most ranged match ups you are not able to AA the enemy twice, if at all, making it harder to proc it. That means in poke heavy match ups Comet will be better, examples would be or.

However, Electrocute will provide you a better mid game with it's superrior damage. So taking it in match ups, where you have to counter a strong mid game and where bad trades in lane are not as punishable, can be worth it. Electrocute can, for example, be a good pic against assassins who are not weak early on like or.
