We had electric for the past 15 years and bought a home with gas. We lasted a year before wanting to go back. The pollution point was enough to give us the reason to go back. Electric cooktop look better, are easier to clean and they don't have a burner smell. I am an asthmatic so pollution is a concern (we have multiple air purifiers throughout the house), and these studies were enough to convince us that going from gas to electric may not help, but it wouldn't hurt.
