How Should I Snowball-Build as an AP Midlaner?

How should I build to snowball an early lead? Suppose my usual build is

And that I got first blood in lane before Lost Chapter.

Here’s are my two possible builds

AP Rush

1. Recall and buy The Dark Seal and, if I have gold, an Amplifying Tome or consumables.
2. Finish Luden’s Echo.
3. Buy Sorcerer’s Shoes.
4. Buy Oblivion Orb.
5. Upgrade The Dark Seal to Mejai’s Soulstealer if it’s stacked.
6. Buy a Needlessly Large Rod and continue into Deathcap if I have enough gold, or buy a Blasting Wand and continue into Void Staff if not.

Not finishing Luden’s Echo saves 1,900 gold, which is enough for Sorcerer’s Shoes and the components of Oblivion Orb. However, I would lose 10% CDR, the passive, and some flat mana. Which of these builds is generally better, or is there another way to do this?
