Induction hobs are more controllable than ceramic hobs, but are typically more expensive and may require a higher rated electricity supply. "Electric" hobs can be induction, ceramic or plain old hot-plate so you can't write off all electric hobs if you've only used a slower type. That said, gas on glass hobs are very popular as they look a bit sleeker than your average gas hob and are easier to keep clean. They're not much dearer these days either.
Worktops. Granite and Quartz are similarly low maintenance and heat/stain resistant (granite is arguably better when it comes to stains), but Quartz offers a wider choice of colours and should be cheaper. A good alternative are surfaces that are half way between laminate and quartz. These have a thin layer of quartz over a core material (wood, chipboard or other material) and can be cut and fitted on site like laminate by a competent or experienced fitter with the right tools. The quartz layer is approximately 6 - 8mm thick and has the advantage of shorter lead-times (off the shelf and no templating or pre-fabricating) and lower cost.
I'm in the kitchen industry (25 years) so won't mention any brands although I'm not tied to any manufacturers.
