When to use `use` or the fully qualified name

I'm wondering when to use the fully qualified class name or when to put a use statement on top of the class. For example:

namespace App;

use Illuminate\Database\Eloquent\Model;

class ImageStatus extends Model {
    public function image(): \Illuminate\Database\Eloquent\Relations\BelongsTo {
        return $this->belongsTo( \App\Image::class, 'id' );
    }

    public function user(): \Illuminate\Database\Eloquent\Relations\BelongsTo {
        return $this->belongsTo( \App\User::class, 'id' );
    }
}

At the moment I have this piece of code and my PHPStorm tells me Unnecessary fully qualified name. This hint disappears when I change it to:

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsTo;

class ImageStatus extends Model {
    public function image(): BelongsTo {
        return $this->belongsTo( \App\Image::class, 'id' );
    }

    public function user(): BelongsTo {
        return $this->belongsTo( \App\User::class, 'id' );
    }
}

So I'm wondering what the difference is, performance wise, code readability and if one is better than the other.

When you do use SomeNamespace\ClassName than you do not have later append \SomeNamespace to ClassName. So your example should be 

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsTo;

class ImageStatus extends Model {
    public function image(): BelongsTo {
        return $this->belongsTo(Image::class, 'id' );
    }

    public function user(): BelongsTo {
        return $this->belongsTo(User::class, 'id' );
    }
}

Please note that when you are in same namespace, than you do not need to add namespace to class name. When namespace App; then User::class instead of \App\User::class
