The three that I've flown extensively are pretty easy to rank.
1) MU-2 (esp. the -60). Faster than the dickens, great big 1960s panel with about a billion steam gauges, switches, etc. Tiny little wing for a good ride and good speed down low on the shorter legs. Lands on a dime, and instant, kickass reverse with the Garretts. Wildly effective flaps, and provided the engines are set up correctly and you have someone who remembers how to work on the avionics/older-than-dirt systems rather than just throw parts at the problem, the rest of the airplane is extremely robust with high dispatch reliability. The spoilers take a little bit of getting used to, and it's heavy in the roll (although not nearly as heavy as a PC-12/45), but once you get used to it, it flies like a dream. Good gear, and a pretty easy plane to land well. Goes faster, lands shorter, burns less fuel, costs less to acquire, and is lightyears cooler and better looking than a KA200. Even these many years on, easily the best plane I've ever flown. Oh, did I mention that it's LOUD?
2) PC-12/45. Fantastic short field airplane. Great cabin. Also reasonably robust, provided your MX knows the Pilatus. Simple systems, pretty decent factory support. Good speed on very little gas, PROVIDED you can get it to altitude. This is not the ideal aircraft for bouncing around at red line and low altitude, due to the huge wing and associated low wing loading (it's like riding a steel girder in anything more than light chop). LUDICROUSLY easy to land. You can do just about anything short of carrier-land it and get compliments from the back. For me, coming from steam gauges and then an FMS, the switchology took a while, as it's one of those "neither fish nor fowl" EFIS setups. You'll spend a fair amount of time trying to get a handle on what's talking to what and what the various systems "know" based on what buttons you're pressing, but once you figure it out, it's all reasonably logical. It is, as mentioned above, awfully heavy in the roll, but it's good for the muskles. Excellent airplane, but just doesn't have the elan of the Mitsi. Or the freaking NOISE. Or the other spinny thing out there to keep you cool.
3) BE-99. Flying box of flaming poop. Think of a King Air 100, then remove the few things that were right with it. No pressurization, no freaking TRIM WHEEL, no A/P, slower than Christmas in January. It's like Beech had a Christmas Party where everyone got drunk and asked themselves "what could we inflict on those jackass pilots?" Easy to fly, but not especially easy to land smoothly (safely, yes, smoothly, not really) due to the afterthought gear. Tiny little wheels just waiting to flat spot or even blow if you're aggressive on the brakes. As a result, it doesn't stop especially well, either. I will say that it climbs like a raped ape at anything less than gross. And that's about the best thing I can think of to say about it.
