Mechanical vs. electric fuel pump?

kinda sounds like an echo of my father LOL...well you know how i feel about your opinion dave....i was kinda leaning towards the mechanical in the first place but thought what the hell go electric....but who knows when ill get around to my new upgrades, so i think ill stick with a mechanical for now...depending on how much a stock one compares in price to the carter strip pump i will decide which i will pick up from there...thanks for all the opinions and input guys!

Stock pump= $16-$18

Carter muscle car pump $33.99
Carter strip $99.00
