Which is better for rainy rounds?

The G-ROK. It is rated IPX7 waterproof and dustproof, and the Ampcaddy lists no water rating. If you play in wet weather, the extra $19 buys real protection.

Which has the longer battery life?

The G-ROK, at up to 24 hours from a 7,500 mAh battery versus 20 hours for the Ampcaddy. Both cover multiple rounds on one charge.

Is the G-ROK worth $19 more?

Yes if you want waterproofing, a 49 lb magnet and an SD card slot. No if you only need basic Bluetooth sound and want to save money.

The Ampcaddy lists 15 W max, the G-ROK lists 8 W per driver with 30 W audio power. Wattage ratings are not measured the same way, so try both if volume matters.

Does the Ampcaddy need a metal cart surface?

No. It comes with a mount, while the G-ROK relies on its magnet sticking to metal. That makes the Ampcaddy easier on non-metal carts.

Which is easier to carry?

The G-ROK at 502 g and 6.5 in tall. The Ampcaddy is 11.2 in tall, which takes more room in a cart basket or bag.
