5mm GT2 are marginally stronger than 5mm HTD, but note that these sprockets are 3mm GT2. They will not be suitable for drivetrain loads.
9mm wide GT2 (5mm) is VERY borderline for an FRC drivetrain, as it's only rated to around .8 HP at typical WCD high gear wheel rpms (1000+rpm)(with common 24T pulleys). 2 CIM gearbox can output peak ~.9HP. You would need to step up to at least 26T pulleys to meet this requirement with 9mm belts.
