Sentinel 3 vs MODIS Land Surface Temperature

I have recently started looking at the new Sentinel 3 Land Surface Temperature data and was somewhat disappointed because I was hoping for some dramatic change in resolution compared to the MODIS Land Surface Temperature but it seems like both products have aprox the same resolution, 1 km.

So what’s the point with Sentinel 3 LST if it’s not larger scale than MODIS?

I think this answers your question.
