I agree, that the TS590S is much easier to use than the FT991, has a much better internal tuner, and a slightly better receiver. It is probably the most intuitive radio to use on today's market. The noise blanker is ok in it, could be better. Still, one of the better radios out there.
The Icom 7410, which I have used briefly, is kind of an unsung hero. You don't hear that much about them, they aren't that flashy, but seemed pretty good. I had an Icom 9100 which was like the 7410 with 2m and 70cm on it, and the tuner in it burned up after a couple of days. That kind of turned me off from that line. The tuner in my FT991 quit on 17 meters as well after a while.
Now using a Yaesu FT450AT. Pretty basic, very easy to use, and since I do mostly FT8 it is good enough for that, especially since it cost me less than $400.
