Indeed. I'm actually using my recently acquired Tek 2225 a lot recently instead of my Rigol. The noise is horrific at low signal levels on the Rigol and the jitter isn't that great either.
If noise and jitter were amazing on the Rigol then there wouldn't be more expensive 'scopes on the market. $350 would be good enough for everybody.

Still I don't think you can beat it for value for money. It does most of what it is supposed to do very well
Exactly. If you draw a scatter graph of bang vs. buck then the DS1054Z stands out by a mile. For the last three years you had to spend $1000 to get something with more overall bang (mostly due to the DS10954Z's hackability).
Since last week that $1000 is down to $500 and we're all winners! Thanks, Siglent! People who need more than the Rigol finally have an option.
But ... 40% more money is still a
lot more and the Rigol is still more oscilloscope than most hobbyists will ever need. Most oscilloscope work is just looking at wiggly lines on screen and the Rigol delivers just fine in that department.
