I think a proper landing is on the centre-line, in the touchdown zone, upwind main gear first (or both together), wings level or banked into wind, appropriate pitch, idle thrust and speed reducing to VRef. I haven't mentioned smooth, because that's just a bonus. We don't want "heavy" (and I question the validity of TC-DCAs numbers); "gentle" and "firm" are the adjectives I like to describe my landings and if I bounce a little bit, then so be it.
But returning to the OP, there could be a reason for EasyJet's style of landing. I'm thinking of their FDM programme and their tea & biscuit sessions when they cause an event. I bet one of their FDM traps is a decceleration rate. Brake too hard and the next call you receive on your mobile is the office.
