If you´re going to have a choice, I would say choose gas, but I´ve got a leccy one which is fine once you get used to its little foibles....
If you´re using electric, the best thing to do is to buy an oven thermometer to make sure you´re at the right temp. Mine seems to get over hot, so always have to knock about 20-30 degrees off the time suggested in the recipe, or the sodding things burn on the top.
