Well depends on your weather, and if you have freezing weather do you want a year-round allseason or separate summer/winter tires, how much you're willing to trade tread life for better performance, etc...
My experience with recent allseasons is also limited. For a long time now I've mostly used summer tires, and when I had real winters, I used separate winter tires (preferably on separate wheels). But that doesn't mean an allseason is wrong for everyone or every situation, sometimes they're the best option.
We have some non-performance allseasons on our Model S right now that still perform way better than the MXM4 did, better grip and road feel dry and wet, much better driving confidence. However they're a bit loud on the highway so I hesitate to recommend them, though it's very possible what we're hearing is from a mechanical issue like that car's bent wheels (yes seriously, and don't ask, they are holding air just fine tho and no vibrations), haven't isolated it to the tires.
Our M3P has been strictly on summer performance tires.
If we ever take it in the snow I'll get separate winter wheels + tires for it...which could be snow-friendly allseasons, or real snow tires, TBD depending on planned use / circumstances.
Edit: Basically I have enough experience to say I really don't like the MXM4 (did try them once on our S, never again!), and I'm pretty sure I wouldn't like the Kinergy GT either. But unfortunately I'm not the best to give advice on better non-performance-focused allseasons.
Now if you want performance tires, i.e. you're willing to give up some tread wear for that, let me know...
