That's far from an old thing - gas ovens are still in wide use, at least in the UK, and recipes will commonly mention both a temperature in degrees and the appropriate gas mark. Having said that, gas ovens are a pain to use until you've got used to the one you've got. I've never had one where the actual temperature of the oven matched the gas mark it was set to. Typically you'll have to benchmark it with an oven thermometer and then adjust whatever the recipe says to fit. Gas hobs however, you can take from my cold dead hands. I'd rather use a camp stove than an electric hob. Nothing beats instantaneous heat adjustments.
