Electric vs. Mechanical Fuel pump debate

I'd like to open up a debate on the pros and cons of electric fuel pump vs mechanical fuel pump. Engine spec: 340 750 Holley carb 410hp

I am planning my fuel delivery system and noticed some liked the summit gig (Goody) and others tried it and didn't care for the whine (63dartman). My car is a convertible so I guess I may hear the electric pump a little more if it is under the car near the tank. The kit seems really complete and the price is nice.

I priced out both setups:

Electric kit from Summit including the tank to filter accessory and the pump the carb setup. approx $310.

Ported Mechanical Carter Hi-Flow Pump (from FBO $160) with 3/8 aluminum lines from tank to carb was about the same price if using the nice -AN fittings. Seems like more of a headache with bending and flaring the tubing, etc

What do you guys think about the fuel setup for this street car?
