It would have to be the Corsair. It's got plenty of space for a crew, but can also be flown fine solo. A lot of DPS, and space for a fury, a cyclone, and a hoverbike all at the same time.
It can lose an engine, but with VTOL or disabling the opposing engine you can still fly straight until you can get it fixed.
I love my Star Runner and plan to make it my main ship when the true complete insurance is implemented. But my most memorable flight is a chill flight over microtech on Super Hornet enjoying the view. I overlooked that ship for years but the feeling and the cockpit view is the closest to real plane right now.
I really like the MISC Reliant (Tana) experience. Having a wing that you can put either vertically or horizontally, makes that much more interesting than any other flying potatoes, especially in atmosphere :-)
I love love love the Reliant especially the Tana. Its so small but has so much teeth! And its variable geometry gives it a very interesting character.
I used to love flying this around when it first became flight ready. But it also very busted back then. The slightest hit and you would loose all control.
So far, the Pisces R: utility, maneuverability, acceleration.
Pisces X is my go to utility vehicle.
The Origin M50 is unbeatable for joyriding. It's extremely fast but still very manoeuvrable, and the cockpit view is great.
Drake Cutlass is the do anything, and it's the one that feels like a space ship instead of some space plane. Wish the pilot seat was the rear one and the engines would rotate a full 180 though instead of just VTOL.
Mustang Alpha.
I love flying the Khartu-Al... My favorite ship to just zip around in.
Very much depends... I enjoy taking out the Origin Jumpworks 135i on moons and planets when going for loot. 6SCU for a ship this size is really great and the ability to store it away at outposts is the best. Won't give away that another player is around and cannot be destroyed/taken by others.
Otherwise the Mercury Star Runner. Plenty of space, living room, stores ground vehicles while still not too big. And the Nightrunner skin is perfect...
