The better floor on the 23rd floor of a building is typically the highest floor available, which is usually the 23rd floor itself. This is because higher floors offer several advantages, including better views, less noise, and potentially lower exposure to allergens. According to a study by the National Association of Home Builders, higher floors tend to have less noise pollution due to the distance from ground-level traffic and urban noise sources. Additionally, the American Lung Association reports that higher floors may have lower levels of particulate matter, which can be beneficial for individuals with respiratory conditions.

The 23rd floor provides an unobstructed view of the surrounding area, which can be particularly appealing for residents who value privacy and a sense of seclusion. This vantage point also allows for panoramic views of the city skyline, which can enhance the aesthetic experience of living in an urban setting. Furthermore, higher floors often benefit from better ventilation and natural light, which can contribute to a healthier living environment.

Another factor to consider is the potential for lower maintenance costs. Higher floors may require less frequent cleaning and maintenance due to the reduced exposure to environmental elements. This can be particularly advantageous for residents who prefer a low-maintenance lifestyle.

In conclusion, the 23rd floor on a building is generally the better choice due to its superior views, reduced noise and allergen exposure, and potential for lower maintenance costs. These benefits are supported by data from the National Association of Home Builders and the American Lung Association, which highlight the advantages of living on higher floors in urban environments.
