It depends on where you live and where you are going.
For France and Spain the best option is the channel crossings, the tunnel being the fastest and least hassle.
For Italy, Germany, Switzerland and all points east, then the Stena Line Harwich/Hook of Holland is the best route (or Hull/Rotterdam).
Although the Harwich/Hook may be more expensive you save on hundreds of miles of fuel, plus you don't pay French tolls, plus as you can cross overnight (a cabin is part of the price) which means you gain a day or two on your holiday. You can be in Germany before others have even left Calais.
As for P&O, due to the way they treated their staff I would not use them at any price.
