Its a $10 difference between the two, so not going to break the bank, but its up to you if the features are worth it.
A side-to-side comparison
shows they have almost identical core features.
The Deluxe has Bluetooth, the external USB 3.0 box, and dual ethernet ports.
The Sabertooth has it's TUF Thermal features and 2 more years on the warranty.
Slaymate is currently using the Deluxe, so he should have some better insight as to what else you get for your $10.
