I vote electric because, as pointed out earlier, they move more air at a standstill. If you have AC, it won't heat up when you stop with good efans.
What relays are you going to use? I got a set of fans from a 2000 Malibu they look the same as yoursUpdate: The other day, I bit the bullet and removed the clutch fan and shroud from my '87 El Camino with stock 305 and 2004r. The plan has always been to replace the clutch fan with an electric dual fan setup from an 2000 Camaro. With the shroud removed, I dropped the efans in for a test fit and secured the top with a radiator retainer from an '87 442. I still have to install relays and wiring.

At speed it doesn’t get hot enough for the fan to even run maybe I got luckyWhile the flashing may help draw more air across the radiator at a standstill (I bet it's negligible at best), it will block airflow at speed. I ditched the stock duals off of my C5 Corvette for a large single Spal fan and the temps went from 194 to 187 at speed. At a standstill it draws more air than stock over a smaller area. The car never gets hot and the AC still blows ice cold.

Well if it’s overheating like you say then the temp center she turn the fans on and they will run whether I’m at speed or notBy design the fan shouldn't need to run with the vehicle at speed. The efan cannot flow anywhere close to the amount of air that is moved at speed. This is why factory calibrations turn the fans off around 30-40mph.
