Grohe vs Hansgrohe taps

[shopper150]

Is there any difference in terms of quality or warranty between the above two? I know they are the same manufacturers, but I wanted to check if hansgrohe was the 'premium' brand, or are they the same, just different designs?

Thanks for that.
I just googled it, appears as though they are not the same company!

Can someone help me? Will the above kitchen mixer be OK for a low pressure system?
