Electric ovens and gas ovens are very different- in operation, in cost and in the finished baked product.
There are a few post on this already however in a nutshell, gas is cheap, quick and good for baking most things.
Electric is more expensive to operate, takes longer to reach temperature however produces a far more stable and accurate temperature, heat distribution and humidity- and therefore typically a better finished product- especially when talking about pastries.
Gas ovens need a lot of airflow through the cooking chamber to keep the flame burning and to get rid of the exhaust gasses. This affects stable temps and humidity as it is constantly trying to heat up cold air as the hot air exits. Its un unstable environment compared to a more sealed electric oven. Fan forced, reversing fan, steam injection and so many more features make electric ovens/combi ovens/deck ovens very versatile!
