Rigol DSO2302A or DHO1072?

In the market today you do need to consider the HD oscilloscopes that are around the corner from Siglent and Rigol. They are popular brands for good reason. Risking some kickback here, I'll stick my neck out and say that Rigol emphasise novel design and feature count (maybe overreaching themselves sometimes) while Siglent appear to have a magic touch for low noise design and max-ing performance (bandwidth, FFT, Bode plot etc) in cost effective hardware. Rigol have a strange habit of keeping older designs in production forever, which has led to a bizarre overlap of features and prices, as you have discovered. Both of these brands have very high % second hand resale value so you don't take much risk if in the end you want to move to something else. I'm not sure what is like in your region, but in the UK GW Instek are over-priced, their products are available rebadged as RS Pro but not super-competitive. The differentiated product qualities and user experience of Keysight, R&S highly respected but Keysight have made it clear they are not doing hobbyist market any more (they hiked 'entry level' prices up by c. 25%, just to be sure), and bandwidth and other upgrades tend to be super expensive if you have to add them later. Tektronix still have an affordable entry range in the TBS series, but it has no memory or feature enhancements at all -- don't expect to find decoders there.

Not only in the UK.
The price/performance/feature ratio is simply poor and most models are also rather old-fashioned.
I recently had a look at the GWInstek portfolio and came to this conclusion.
About Keysight, Lecroy (Nico had forgotten to mention), Tektronix we need not talk as hobbyists.
If these brands offer something in our price range, then you might as well go for the "original" and help yourself to the China man.
Or, what they offer for "little money", for the money I get somewhere else incomparably more and better.
R&S takes a special role here.
But even they have nothing "cheap" to offer.
No, in the range up to 1000€/$, and I assume this for the topic creator, there is no way around the two top dogs Rigol and Siglent.
Then he wants to have 12Bit, only Rigol remains at the moment, because the "small" Siglent 1000 HD is not yet on the market.

Until you actually start using one, you'll find out their oscilloscopes are very nice & efficient to use. A lot of thought went into making the user interface efficient and clear. And no surprises with features that don't work or are not quite right. The same goes for the Tektronix TBS2000 series. Once you use one, you'll quickly appreciate how well they work.

The biggest mistake to make is to select an instrument based on the longest list with features and forget about quality of implementation. A feature you never need is worth nothing while a user interface that keeps getting in the way of your work is a nuisance forever.

So when selecting an oscilloscope with a limited budget, it is very important to have a clear list with requirements and buy the one which is most suitable. Nothing more and nothing less. Even better: create list with tests and test whether the oscilloscope (or any piece of equipment) you ordered meets your requirements. This helps to understand the instrument and return it when it turns out to be a dud.

The perfect oscilloscope does not exist. At the moment I own 5 oscilloscopes (from cheap to very expensive) and every one of them can do something special the others can't.

BTW: I specifically left Lecroy out because their scopes are more geared towards analog signal analysis and thus are less usefull for general purpose digital / analog debugging work.

However LeCroy pricing vs OEM is another matter.

None of those are real Lecroy scopes! Lecroy always has been rebadging other brands (like Iwatsu as well) to fill in the gaps in their lineup; especially at the lower end. And you known that very well.
