Go gas! I know that energy costs are rising and all that, and gas is also getting more expensive. But if you really want to create in the kitchen, gas truly allows greater flexibility.
Modern stovetops can heat up almost as quickly as gas, but the degree of control is still finer with gas than with electric. Also, when you get good enough if you need to flambe, it's easy to just tip your pan and let your gas flame touch your liquid contents. When cooking with gas you don't feel any qualms about moving items around on your stovetop either. With electric, once an element is heated up properly I kind of feel obliged to keep using it rather than heat up the other elements. With gas you just tirn them on and off at will.
The flat tops are great for aesthetics and easy of cleaning, but true mastery in the kitchen requires gas.
