Which pans specifically though?
I’ve usually had cheap non-sticks from Argos and it’s not been a problem getting stuff off them at all, although the non-stick will wear away after a while (quicker if you use metal utensils in them).
If yours aren’t non-stick and instead are just metal like this:
then stuff will stick to it but on the other hand you can clean that fucker with one of those metal scourers that would rip non-stick off a pot

That should clean a stainless steel pot up nicely.
Obviously make sure you’re soaking them in hot soapy water as soon as you’re done to help lift the dirt.
One thing more expensive pans have is very heavy bottoms that distribute heat better. Even so I think most gas rings burn too hot for me unless you are lucky enough to be using a very new hob so probably just keep the heat very low.
You can even buy one of those cast-iron hob reducers to help out
