Unity GameObject Extensions for human-readable code when working with 2D transform positions

My2DExtensions.cs

public static class My2DExtensions {    
    public static bool IsLeftOf(this GameObject t1, GameObject t2)
    {
        if(t1.transform.position.x < t2.transform.position.x){ return true; } else { return false; })
    }
    public static bool IsRightOf(this GameObject t1, GameObject t2)

    }    
    public static bool IsCenterOf(this GameObject t1, GameObject t2, float wiggleRoom=0f)
    {
        if(t1.transform.position.Distance(new Vector2(t2.transform.position.x, t1.transform.position.y))<=wiggleRoom) return true; else return false;
    }
    public static bool IsAbove(this GameObject t1, GameObject t2)
    {
        if(t1.transform.position.y > t2.transform.position.y){ return true; } else { return false; }
    }
    public static bool IsBelow(this GameObject t1, GameObject t2)
    {
        if(t1.transform.position.y < t2.transform.position.y){ return true; } else { return false; }
    }    
    public static bool IsMiddleOf(this GameObject t1, GameObject t2, float wiggleRoom=0f)
    {

/* Usage in another script:
if(thing1.IsLeftOf(thing2)) Debug.Log("It's to the left");
if(thing1.IsAbove(thing2)) Debug.Log("It's above");
if(thing1.IsCenterOf(thing2, 0.5f)) Debug.Log("It's centered within 0.5f horizontal distance");
if(thing1.IsMiddleOf(thing2, 0.5f)) Debug.Log("It's centered within 0.5f vertical distance");

A few more for transforms and Vector3s, with optional and named parameters, which results in good readability:

    // Usage:
    // transform.localPosition = transform.localPosition.With(z: 4f);
    public static Vector3 With(this Vector3 source, float? x=null, float? y = null, float? z = null)
    {
        float useX = x.HasValue ? (float)x : source.x;
        float useY = y.HasValue ? (float)y : source.y;
        float useZ = z.HasValue ? (float)z : source.z;
        return new Vector3(useX, useY, useZ);
    }

  // Usage:
    // transform.SetLocalPosition(z:4f);
    public static void SetLocalPosition(this Transform tr, float? x = null, float? y = null, float? z = null)
    {
        float useX = x.HasValue ? (float)x : tr.localPosition.x;
        float useY = y.HasValue ? (float)y : tr.localPosition.y;
        float useZ = z.HasValue ? (float)z : tr.localPosition.z;
        tr.localPosition = new Vector3(useX, useY, useZ);
    }

public static void SetWorldPosition(this Transform tr, float? x = null, float? y = null, float? z = null)
    {
        float useX = x.HasValue ? (float)x : tr.position.x;
        float useY = y.HasValue ? (float)y : tr.position.y;
        float useZ = z.HasValue ? (float)z : tr.position.z;
        tr.position = new Vector3(useX, useY, useZ);
    }
