Ezreal build comparison of double tear and regular build

So i decided to go into a practice tool game and used runes that would not benefit him any damage and compared a couple of builds to see which is more effective. These are the stats i decided to take note of cause they seemed most important to me. These were all tested on the Practice Dummy which has 100 armor and 100 Magic resist

Double tear build - Stats:

• 319 Attack damage
• 162 Ability Power
• Q damage - 1052
• Auto attack damage - 799
• Ultimate damage - 505
• Muramana - 74 AD from mana, Seraph's Embrace - 112 AP from mana
• Total damage from those attacks =2356 damage
• Total Cost = 16,233 Gold

A normal build - Stats:

• 371 Attack damage
• 0 Ability Power
• Q damage - 999
• Auto Attack damage - 782
• Ultimate damage - 458
• Muramana - 46 AD from mana
• Total damage from those attacks =2239 damage
• Total Cost = 16,733 Gold

Differences: Double tear gives 117 more damage from those attacks, cost 500 gold less, will take longer to get to that point due to stacking both tears Double tear will give more mana and will grant you a very big shield.

I mostly did this just because i was curious if the trade off was worth it or not to just buy a strong attack damage item or spend time stacking both tears, and this does prove that it is more worth it to buy both tears, even when i swapped out Seraph's Embrace for a fully stacked The only thing which did more damage was the Ultimate by 5 damage.
