My twopence or is it 2 cents worth.  The 570 is a nice rig.  I've used it on
several DXpeditions with great success BUT I agree that it doesn't quite
come up to snuff as a serious contest rig.  Why?  Well for my money, it's
because the filtering isn't good enough.  In the 570 the DSP is at audio
frequency rather than at I/F as in the 870 and you can only add xtal
filtering in the 8 MHz I/F which means the shape factor isn't too
impressive.  With the low cost ceramic filtering it uses nearer the front
end it may be prone to overload, though in practice I haven't noticed a
problem there.

That aside the 570 is a good radio for most uses and it has some nice
features.
