Depends on what you actually want to do, and what you think you need to carry along for the ride.
Yes, the 'conda is the undiputed queen of jump range, together with the DBX. The latter is hampered somewhat by the small scoop - and by the fact that once you add everything you might need on the trip, the jump range doesn't look that good any more. Downside of the 'conda is, well, it's a 'conda. Turns like a barge, and is equally hard to park.
If you don't insist on a 50ly+ jump range, a lot of other ships come into play - AspX, Hauler, Dolphin, Orca all can reach 40ly+ fully equipped, including a SRV. For exploring, I like the Dolphin - good view, roomy cockpit and can land on a towel. The Orca will handle dual SRVs. The Hauler is a bit limited in internals and in any case won't haul much if you want to keep the jump range over 40 ly, but is the most agile of the lot in both SC and real space, and can be the fastest in real space. Plus, it scoops even faster than the 'conda.
