One really good thing with the finalist algorithms is that they all provide authenticated encryption. For many IoT systems, authentication and integrity protection is way more important than condidentiality. Many older lightweight algorithms (or AES) for that matter requires adding either an authentication mode, or another primitive (a hash function used in HMAC for example) I believe that has led to a problematic proliferation of only having confidentiality protection in too many IoT systems deployed. These candidates makes it easier for developers to add the security properties their system actually needs.
