Just a note...
o Low profile lips are great re aesthetics
---- Franke come to mind here
o Low profile are a pain re splashing water
---- because it will permanently end up up all over the worktops & floor
o Low profile don't hold anything within them
---- any high water level, spills, dishes all slide over the lip

So if going for low profile...
o Ensure any worktops have laminate rolled under the edge
---- otherwise they will expand & shed due to moisture under-run
---- modern laminates do, just something to be sure of
o Use a proper height tap
---- so you can get a cordless kettle under it, milk bottles under it
---- not with the sink empty, but with the sinks full to the top

Yes Franke are nice - and you do want 1.5 bowl option.

Installation notes...
o Ensure the overflow is connected correctly & watertight
---- or you get small but continuous water damage to the surface below
o Ensure the sink sits down on the worktop & seals
---- particularly at the rear, because otherwise water ingress occurs
o Ensure the tile-to-worktop area behind the sink is properly sealed
---- it will be regularly splashed, many sealing strips are poor
o Measure the supplied plastic bowls & note their part numbers
---- many Franke use odd sized bowls re no others will fit :-)
---- either re physical size or curvature - Franke are 55-70ukp/set

All pretty obvious, but low height taps are a right pain with a Franke.
High profile sinks can look quite ugly & cheap, but more practical :-)

As for longevity the Franke ones are decent thickness, high grade,
and will last a lot longer than anything not built out of granite :-)
