I had considered outfitting/engineering a DBX for minimum heat generation and try to see how close I could get to certain things, like a neutron star, or a black hole, etc. That heat management is excellent.
Same reason why someone would choose a Sidewinder over a Cobra... not having the money for it.
The Diamondback Explorer really excels as a fast mission runner or smuggler. The ability to land on small pads means that outpost docking can be faster as you rarely have to wait for a small landing pad and the heat management means it is better at silent running. It's also easier to find a landing spot in rough planetary terrain as it is substantially smaller than the Asp. The jump range with an equivalent FSD is actually slightly better than the Asp using a similar loadout as well. The Diamondback Explorer is however notably slower than the Asp (typically 50 m/s difference in max boost with similar setups) and it doesn't really have the internals to do proper exploration outside of the bubble (not enough slots for a ADS/DSS/AFMU/SRV/cargo/fuel scoop simultaneously) and can't mount a large fuel scoop like the class 6 slot you have available on the Asp.
I know it's controversial as there's a lot of love for the DBX, but other than the price difference, why would anyone choose it in favour of the AspX?
I've never owned a DBX, but on paper the AspX seems to beat it on most stats.
Sell me.
I have the money for an AspX, and prefer my DBX for multiple reasons. [???]
can't say I've ever needed an AMFU while exploring. Out for 4 months one time, came back with the lowest module at 90% damage.
The DBX has 1L HP. By the numbers the ASP outguns the DBX. In real life it doesn't.
What the DBX has going for it ... it's considerably cheaper both to buy and outfit.
