Where each product wins
The rod holder wins on price and mounting flexibility: its clamp can grab a range of rail and frame sizes, so it adapts to boats, bikes, kayaks, and chairs. The cup holder wins on utility: it not only holds two drinks but also has a compartment for a phone, wallet, and keys. If you need to secure rods at any angle, the 360-degree rotation is the standout feature. If you need your essentials within reach, the cup holder's storage compartment is the standout.
Marine Boat 2 Cup Holder Cupholder Starboard ST

Choose this if you want a permanent deck companion that does more than hold a can. The King Starboard ST body is built for marine environments, and the design accepts YETI tumblers, bottles, cans, and cozies. A storage compartment is large enough for a phone, wallet, and keys, so you can keep essentials off the deck. Mounting is flexible: you get stainless steel screws and four suction cups, and the suction cups avoid a common weak point because the screws don't pass through them. The main limitation is size: at 9.00" x 4.25" x 3.50", it takes up real deck space, so a crowded console might not have room. Measure your deck before committing.
Fishing Rod Holders for Boat Rod Holder 360-degree Kayak Rod Holder Side Deck

This one is for anglers who are always moving. The clamp fits rails and frames from 0.59"-1.57", so it works on a bike, boat rail, camp cart, fishing chair, or other poles. The 360-degree rotation and multi-angle adjustment let you point the rod where you need it, making it easy to troll, paddle, or just keep your hands free. It's made from ABS, so it's lightweight and won't add much weight to a kayak or small boat. The tradeoff: it doesn't hold anything but a rod. There's no built-in storage or cup accommodation, so if you also need to stash a phone or drink, you'll need a separate holder. For rod management on a rail, it's a solid, straightforward option.
