I am a Yoder YS640 owner and I absolutely love it. By all means, get it with the competition cart. Its 450 pounds heavy but on the competition cart it moves easily. I've never had any issue with mine and it still looks as good as when we rolled it in to the back patio. I have the custom cover it comes with to keep the weather at bay.I can't speak to the others, but I have a YS640 and have had it for 5 years. I don't run a blanket in the winter and I live in the midwest. I have never had a problem with it running in cold weather. In my opinion, they will all take about the same time to warm up and settle in. It's just part of the process. I'm sure I use more pellets in the winter, but I can't quantify it, and it's not enough for me to really notice. I've also never had to repaint anything, but mine stays in the garage and I roll it out to cook on it. I would definitely recommend the comp cart if you plan to move it around at all.
Like many here have said, with the units you are considering you can't go wrong. They will all get the job done and look great doing it. This is one of many great choices.
