80% slopes, edges and zero-turn compromises?

So I'm looking to buy my first robotic lawnmower. My yard is not that big, perhaps 600m2 (0.15 acres) across two zones separated by a wooden deck. And it contains two 80-85% slopes, lots of edges, somewhat rough uneven surface and is bordering towards forest area meaning cones and twigs are common.

I value having low-maintenance ie less trimming, less helping it get unstuck, less tearing up the turf and imagine a more powerful mower means less twigs etc getting stuck. I will also need it to navigate a 1.5m wide wood deck to reach a second zone.

* Navimow X420 seems like a powerhouse, good app, good brand, but doesn't seem to get even close to the edges meaning a lot of trimming. Also, maybe a bit overkill for my small area.

* Roborock RockMow AWD Z115 seems like a good option with edgetrim-accessory, zero-turn. But seems unproven gen1, and it's RTK. Can't find any experience on it posted online. This make me hesitate.

* Husqvarna 405VE. Reliable brand with good app, but don't do slopes and risk getting stuck compared with AWD-models, only 3 blades but have edgecut-blade.

* Dreame A3 AWD. Do slopes well, have edgecut, but not zero-turn and seems it it would aggressively tear up the grass.

I'm leaning towards the Roborock but basically no hands-on experience available online make me hesistant. All versions above are non-LIDAR, as that saves some money.

Would be happy for any input.
