buy a better oscilloscope than the Siglent SDS1104X-E

Can someone who has these oscilloscopes advise me?

No, because if you don't know what you need then nobody does.
The only answer to that question is to buy the most expensive one and cross your fingers.

Dears,
beside all the pro and contra of the mentioned DSO's
I have obtained a SDS5034X this days due to the higher
sampling rate (5Gs) and the possibility to upgrade it to
a 750MHz BW. Price was a bargain due to a demo device
but with very less working hours.
I hope that later I will effort a HD version and could compare.

You need to provide more detail of work to be performed to get more targeted advice.
Maybe you don't need a "better" scope at all?
What is a type of work you could not do that prompted you to want a "better" scope. Start with that.
Siglent SDS2104X Plus is a 500 MHz scope platform. Low noise, good for both high BW and small signals. MSO. Very good BODE plot.
Rigol MSO5000 is 350Mhz design without 50Ω inputs. It has 2 Ch AWG, 4 decodes. Higher noise and lower sensitivity. It is good for general purpose work, not ideal for fine analog work. For Arduino kind of work decent choice.
Both Siglent and Rigol 1000HD platforms are low BW, up to 200 MHz, so same as SDS1104X-E. They would be very good for fine analog work, but with BW limit.
So as @coppice already said, Siglent SDS2104X Plus is best compromise of all listed, with limited other info...
Even very expensive scopes will never be perfect for "everything". They all specialize something: BW, noise, math, screen size, decoding...That is why people end up with many scopes...

I am designing an antenna rotor controller and I need to reduce the noise from the power supply and the reference voltage for the ADC readings. I need a fairly accurate oscilloscope to see the noise at 600uV or less

I first got the SDS1104X-E then bought the SDS2104X-P for improved bandwidth.
I still have both. I have used the 10 bit mode on the SDS2104X-P and it does work well, but as mentioned limits the BW to 100MHz.
Maybe if you have more specific questions about the scope we could continue to answer them instead of just asking for a general opinion. We all use our equipment differently because will all do different things so our "general opinion" will be heavily colored by our own specific needs and may be meaningless to you, or worse, cause you to make a bad decision.
I will make one comment with regards to sensitivity. The SDS2104x-P's enhanced sensitivity is very nice to have, but it requires that you have a very "quiet" lab environment EMI wise.
