Hi and welcome to the forum..
Both have 2GSa/s, 2 channels and 12 Bit ADC (which I prefer).
No, the DS2302 have 8 bit resolution, 12 bit in high resolution mode, the DHO1072 is a true 12 bit scope.
Besides the bandwidth, there are hardly any points that still speak for such an older scope model.
In the bare data comparison, it is inferior to the DHO in almost all points, if it is only about the two, I would clearly advise the DHO.
However, 2 channels might not be enough for you at some point, I would consider that.
If it is not only about the two, I would consider the (hopefully soon to be released) SDS1000X-HD model (also "real" 12bit).
It doesn't have the higher screen resolution as the DHO and also no hdmi output, but should have "out of the box" the less buggy software/UI, as well as the better FFT function, bodeplot possibility (missing from the DHO).
So, between DS2302A and DHO1072, clearly the DHO.
If something else comes into question, possibly think about the SDS1000X-HD, which unfortunately is not yet on the market.
