Best SMS for Android Tablets

[THE POTZ]

MYSMS is the only sms app that works and syncs well between my tab S and phone. The problem with it is that it's bland with really no customization options. Why do tablets lack in sms app options unlike the phones ? Every one I've tried to download on my tablet either says "not compatible" or have to adjust "permission settings" to allow it access. You can't even access the permission settings on the Tab S. Any thoughts amigos? Frustrated.
