Given the option, and all things being equal I would always choose brick over any type of fake brick. However, if you can find the right faux brick then this type of siding in a home can be a wise choice. The bottom line is that real brick is way more expensive.
In addition to being more expensive, working with real brick is more labor intensive and you will definitely need a professional to construct a real brick wall the right way. My husband and I like to tackle home projects and for us faux brick makes more sense.
