The output is fixed at 1.8 V, so you skip the external feedback divider. That saves two resistors and one feedback node, which reduces BOM count and removes a potential noise injection path on a tight layout.
The TPS62044DGQG4 is rated for 1.2 A continuous output current.
The difference is the shipping medium: TPS62044DGQG4 ships in a tube, while the TPS62044DGQR variant ships in tape and reel. The electrical specifications and package are identical.
