Gear up or down? Gear down if possible
If a taildragger, landing on unprepared (soft or rough) surface, your odds are better gear up, to avoid noseover.
I once had to land a C172 with suspected frozen brakes (slush frozen in the wheel pants). Fortunately part of the runway was still unplowed, with liquid slush - so I chose that as my touchdown zone, reasoning that a messy slip-slide was better than overturning. The owner made me wash the aeroplane afterwards, but no problems otherwise.
