In my area, buyers are looking for stone countertops and now the renters are starting to look for it as well. I almost always put in stone. My stone countertops have lasted longer than any of my laminate countertops as well, so I tend to stick with it.
If you're worried about sealing the granite, I have that as a checklist item during turnover so I don't worry about having my tenants do it. If they end up being longer term tenants I will ask them to do it at certain times. If you're worried about a tenant putting a hot pot on the counter, stone is better because it is naturally heat-resistant. I have never had issues with a stone countertop, but I have had burn marks on a laminate counter from a tenant setting a hot pot on it without a trivet.
With all that said, I would really just go with what the market wants. If laminate is good enough and you still get market rents, go with it. Sometimes putting in the granite will not get you additional rent, but just costs more. I personally would still go granite, but I have used laminate as well based on the place.
