Brandon wants to get a smartwatch to work with his Android phone. Leo says that Android Wear will give him the most choice, but Samsung's Gear 2 and Gear 3 are quite good. The only negative is that he'd need a Samsung Phone to use it.
Pebble has the longest battery life. If fitness is his sole goal, then the FitBit may be better. He could even use an Apple Watch with Android, but Leo doesn't think it's the best fit. LG and Motorola are good brands as well.
