Beautiful remote hamlets. Outside Lewes or Chichester....?

[Somethingtodo]

Looking to downsize to remote rural hamlet with access to nice cultural town and close drive to stunning coastal walks......narrowed it down to outside Lewes or Chichester - can anyone compare the two and the coastline at each - pros and cons?

I stayed in Alfriston for a period around 15 years ago. 15 mins drive to Lewes. Very pretty, although because of that very busy in summer.

Thanks - yes always worth checking out on a hot weekend. Think we have narrowed it down to Nth of Chichester as think that the beach at west wittering is nicer than coast near lewes,
