Gas used to have a reputation of being more consistant than electric.
(maintaining the set temp) and heated faster.
Electric has improved a lot in recent years.
Fan forced convection ovens have their uses in providing an even heat,
so avoiding the 'bake for 10 min then turn pans for the next 10 etc BUT
some convection ovens do a bad job with some baking.
Best option in my opinion is a gas oven with normal / convection modes.
