If you have a gas hob and an electric oven then you would always have the means to cook during an electricity power cut. You may not be subject to many cuts at present but the chance is always there and if it were for a long period you may be very glad of this setup.
Depends on what you're used to. For the last two years I've been struggling with the electric oven that came with this house. Before that I'd always used gas and just got used to it, I suppose. I just find that my food either takes an age to cook or is instantly incinerated at higher temperatures with the electric oven.
Now I can finally afford to get my kitchen redone and I'm detremined there will be a gas hob AND a gas oven.
Stick with what you feel best with.
electric fan oven, and electric halogen hob.
oven because fan ovens are by far the best to heat up and control.
halogen hob as it is really quick and easy to control, and a lot easier to clean than a gas hob (having had both i would never go back to a gas hob).
Gas hob for me - for ease of control. Mine is very easy to clean (just a wipe down), so no problems there. I've used halogen and electric hobs and found them both *tricky* to get used to. I simply like the fact that I can turn the gas ring on and have instant heat and then turn it off and stuff immediately goes off the boil for example.
Oven - definitely electric for me - I find they maintain their temperature better than gas (I've had both and do a lot of cooking and baking) BUT I do have TWO ovens - one normal electric one and one fan driven electric one. These ovens are wall mounted so that I don't have to bend over to reach inside the oven or to see if my bread is ready to take out. The doors hinge downwards so they can be used as a handy place to plonk hot food onto if need be. The standard oven also houses a grill - at eye level - which is quite handy - nothing worse than having to constantly bend down to check if one's cheese on toast is ready !
I am also looking into the newer steam ovens that are around.... for when I can afford to buy one !
I have a separate microwave oven but I've been hearing good things about the combined micro/grill/trad ovens too.
Gas, gas and gas for me. I have a gas cooker at the moment and have cooked the same thing in my cooker and in my Mother-in-Laws electric fan oven, and it taste much nicer cooked in the gas oven. Also I like to cook things at different temperatures, I can have something at the bottom of my oven which is cooking at a lower temperature than something at the top.
Ahhhh, SpudQueen does have a good point there ! I had forgotten that you get different temperatures at different points in the gas oven....(it gets hotter at the top of the oven etc).
