Nicotine salts win on convenience, plain and simple. They're designed for low-wattage pod systems like the LINQ-SLIM or LINQ-ONE. You fill a pod, take a few puffs, and you're good. There's no need to adjust power settings or worry about coil frying. The liquid is usually 50/50 VG/PG, so it wicks well in small devices.

Freebase requires a bit more thought. You have to match the VG/PG ratio to your device—high VG for sub-ohm tanks, high PG for mouth-to-lung setups. You also need to dial in the wattage to get the right experience. It's not hard, but it's an extra step. If you're after a set-and-forget experience, salts are more forgiving.

Maintenance is also easier with salts. Because you're using lower wattages, coils last longer. With freebase at high wattages, you'll be replacing coils more often, which adds to the cost and hassle.
