Jim KX2T,
Having never used a FTDX-10 (nor any Yaesu radio in my 63 years as a ham), I can't render any opinion on it. Maybe I'm a "minimalist", but IMO, I think sometimes these newer radios go a little overboard with features and fine adjustments that put them in a realm of diminishing returns. They just provoke you into constant fiddling with knobs, buttons, and menus in order to try to achieve receive/transmit nirvana

. In the long run, they really won't get you many, if any, more QSO's.
I'm not into ESSB, so any more EQ (RX and TX) than base and treble control is just fluff. As a contester, the less I have to touch the radio controls, the better. Basically, adjust the filter selectivity according to how crowded the band is in order to reject close-in signals, and run with it. For me, the IC-7300 does a great job filtering, going as low as 50 Hz if needed. As pretty as Flex is with the detail and resolution on their panadapters, in a major contest they're just as much a mess of peaks and valleys as a 7300. Really only good enough to spot rogue stations at band edges and finding holes to call CQ.
Mitigating band noise floor is a major factor in your ability to comfortably receive signals. As good as the NR algorithms in the newer radios are, I find my experience with the WMR CLRdsp outboard NR unit as very positive, especially cascaded with lower levels of the 7300's NR.
But what works for one doesn't work for another. Try them out, and go with what is best for your needs.
