Jeepers - some people do make things very difficult. Technically there are differences, but there are so many other variables day-to-day, are you really going to notice? As compressor stall said, the TPs at Airbus have done a great job in smoothing out the different control laws to make them all very similar. There are different laws in take off also between the Neo and Ceo but you'd never know. FWIW I fly most variants of the A320 from knackered old sheds to brand spanking new. The last thing on my mind at 50ft is whether the THS has been frozen by a control law on a particular variant. To the OP, yes there are differences between the Neo and the Ceo.
