I happen to really like my 5.4. I am at 120k miles, bought it with 90k. The 2010 5.4 doesn't have issues. The spark plug thing was cured, I did my plugs no problems. The cam actuators, the other early 5.4 problem is supposed to be fixed as well for 2010, and mine isn't making any bad noises. The 5.4 is easily good for 300k miles. The best part is averaging 16-17 mpg, show me a 6.2 that is that affordable to daily drive. I don't think the power difference is all it is cracked up to be. Torque numbers are not that different but the 6.2 runs higher rpm to get peak numbers. Even at high altitude mine easily passes on two lanes and is a blast on dirt roads. Thinking it is somehow not worth considering is pretty funny after having owned one a while. The car I drove before this was a 500hp Porsche Cayenne turbo. This isn't fast like that but far from a disappointment.
