As for other roles, the Asp simply hands down beats the DBE. It may not have the strongest shields out there but they are still more powerful than the DBE. It's also more maneuverable and offers better firepower, excellent hardpoint placement and more options internals wise. Not saying the DBE is bad at all, it does what it says on the tin, and does it well, but there's a reason for it's lower price; while it's definitely comparable to an Asp in exploration, having it's own, inexplicably vocal fan club in that regards, when it comes to setting it up for other roles is where it starts losing to the Asp. Properly set up, the Asp is a decent little gunship with scary amounts of forward firepower, while still being able to haul enough cargo and have enough jump range to be a great rare trader. It's also quite fast on thrusters only. I understand we get emotionally attached to our ships, and want them to be the best, but realistically the DBE isn't as great as a lot of people want to portray it. Heck, I'm totally in love with my Cobra but do have to acknowledge that the Asp beats it in a lot of ways. I still get sentimental about my Cobra while my Asp is more of a tool for the job. For all things bubble, I simply had more fun in the Cobra even if it gets outperformed by the Asp in firepower, shielding and cargo capacity. It's not always about logical reasons, and that's fine
Lastly, I know people hate the Asp's looks, well I don't really care for the DBE's; to me it looks like a bloated BSG raptor with a yellow, non changeable paintjob. Immersion wise it kind of looks cramped, not the sort of ship I'd want to cross the galaxy in. At least the Asp looks like it might have a comfortable cabin in there somewhere
