I had an FT-857D a while ago, it was the worst transceiver I’ve ever used. The issues were:
CW key clicks, very poor ALC resulting in 100 Watt peaks when set to 20 Watts, noisy receiver making listening fatiguing (hissy), internal CW keyer useless (can’t store AR except as A R to end a CQ call, etc).
I also had the loan of a friends Icom 706G mk II. That had synthesizer spurs every few KHz on receive (symptoms were noisy but strong receive on signals that were clear on an adjacent receiver using the same antenna) it lasted 15 mins in my shack and went back the next day.
I replaced the 857 with a Kenwood TS-480SAT. The only minor niggle (and it is minor) is that when used with a transverter the frequency data sent on RS232 is the HF frequency, not the dial frequency (the radio display shows the VHF final frequency correctly). A second hand 480 can probably be picked up cheaply, they are very well designed and perform well, especially on 6m. They are probably not popular due to the remote head arrangement.
New, the Icom 7300 is hard to beat. There are two issues with them: If you have a fast switching linear, beware that RF continues for 4mS after the linear key line goes low, resulting in hot switching the linear. Secondly, the clock uses a rechargeable lithium battery, if it goes flat it’s permanently damaged and awkward to change... you need to power the radio for 2 days each month.
Most radios have some issues, some more so than others...
