Eh ? Scenery ?? Seriously ?? You don't think much of the simply magnificent views from, say, Firle Beacon perhaps, or above Cuckmere Haven or anywhere along the Seven Sisters are up to much then ? Downland around Alfriston ? (I'm in West Sussex by the way).
He obviously hasn't seen much of the East Sussex countryside.
All of the places you have mentioned have stunning views, I will add the area around Telscombe Village, Bishopstone Village and the views from any high ground around Lewes.
