The central trade-off
Service flow. The Aquasure Harmony 48,000 lists 12 GPM; the other listing doesn't state one.
Warranty. The AFWFilters Fleck 5600SXT 48,000 lists 5 year manufacturer; the other listing doesn't state one.
At an efficient salt setting. About 36,000 grains for the Aquasure Harmony 48,000 and 36,000 for the AFWFilters Fleck 5600SXT 48,000 between regenerations (three quarters of each rating). Check both against your water.
Control valve. The AFWFilters Fleck 5600SXT 48,000 names its valve (Fleck 5600SXT), so its parts are easy to match later; the other listing doesn't name one.
