I have a 7000, and prefer it over its Yaesu competitors. The IF-DSP is simply superior in my opinion to the AF-DSP. Yes, you can add crystal mechanical filters to the Yaesu models, but once you accessorize the Yaesus to a point where they begin
to become competitive with the Icom you start to approach the price point of the Icom out of the box.
That said, the Yaesus, especially the 897, are eminently more suitable for portable operations than the 7k. They all run hot, but the 897 stays cooler. Plus you can get internal batteries for it.
Which radio you prefer depends on a variety of factors. Your intended use, for one. My intended use was a small, full-featured radio that would form the centerpiece of a carry-on mini-DXpedition station. That was in 2008. If I was going to do it today, it'd be a K3.
Another consideration is just playing with the things to get a feel for them. If you have the ability to do so - ham radio store or club members - go and fiddle with them. The worst thing in the world is to buy a rig because of other considerations then hate using it.
Don't forget the other US manufacturer, too - Ten Tec. They have a few models that meet your criteria. The Argonaut
is a QRP radio like the 817, but in my opinion vastly simpler and superior performance. The Eagle
is only a little bit larger and gives you the full 100 watts out. I't actually considering an Eagle for my own shack. I like the simplicity of the thing compared to the layers of menus and relatively complicated access of those menus on my Icom.
Coax loss is only not a factor when your antennas are resonant. If you intend to use an antenna tuner in your shack to tune an antenna at the other end of 200' of coax, you may really only be heating up the coax.
Which leads me to my last thought: All this back and forth about this rig or that rig means positively squat if you don't have an antenna plan. What kind of rig you have, what features it has, its receiver characteristics, none of that amounts to a hill of beans if you don't have a good antenna with which to receive and transmit signals. I'd like to hear more about your antenna plan.
