No they are not all the same. You do get what you pay for but if your needs are simple, and you're not expecting much, go for the cheaper ones.
Cheap ones with warranty are still cheap rotors - you're just paying for the next ones in advance. Most aftermarket parts are marketed the same. They sell the exact same part (with ot without warranty) but expect you to keep all relevant paperwork and meet the criteria to collect the warranty. Sometimes best just to go for the bottom line cheapest part and save the cash for if/when you need to change it again.
Quality brake rotors (OEM Volvo) are excellent parts. The steel is good quality, machining is accurate, they are balanced and they fit properly. They will perform as expected and also last a considerably long time.
You will pay more for them but it's a personal choice if the money is worth the performance.
