...this is a very personal decision, the choice is yours really but for me I wouldn't have any of those you've mentioned... I don't like Cotoneaster hedges, the Pittosporum isn't reliably hardy and not easy to find I think, that particular one..there are other varieties of that but Pittosporum don't look good when regularly clipped as a hedge, in my opinion... the Lonicera is alright but most people plant Baggeson's Gold and I find all that variegation too much for my eyes..
my choices would be... Buxus sempervirens [not the dwarf variety]
Griselinia littoralis, with perhaps the variegated version every 5th plant in the row, just to lighten it up..
Rose 'Iceberg'... deciduous of course but this makes a lovely low flowering hedge...
...just alternatives to ponder..
