Choosing between two stainless steel rod holders for your boat comes down to where you want to put them. The 2X Stainless Steel Fishing Outrigger Holder is built to be flush-mounted and also works as an outrigger arm, while the 2X Marine 316 Stainless Steel Rail Mount Rod Holder clamps onto existing rails from 1-1/4" to 2". Both are new, silver, and priced within about $1.25 of each other, so the decision is really about mounting style and intended use.
Quick Verdict
If your boat has flat surfaces where a flush-mount rod holder can sit, and you want outrigger capability with 14-inch arms, go with the Outrigger Holder. If you have horizontal or vertical rails and want a clamp-style holder you can adjust or remove, the Rail Mount Rod Holder is the match.

Where Each Product Wins
Outrigger Holder
This one is the stronger option when you need a flush-mounted holder that also supports an outrigger. The listed 14-inch arm length and 10.2-inch rod holder length give it a different profile from the rail-mount version, and the features include both saltwater and flush-mount use. It's also the lower-priced of the two at USD 52.70.
Rail Mount Rod Holder
If your boat already has rails, this holder is the clear fit. It's listed to clamp onto rails from 1-1/4" to 2", with a 316 stainless clamp and a 304 stainless tube. The features list includes deck mount, side mount, adjustable, and removable, which gives you more flexibility in positioning than the flush-mount holder.
Product Notes
2X Stainless Steel Fishing Outrigger Holder

Look at this one first if you need a flush-mount holder that also carries an outrigger arm. The listed 10.2-inch rod holder length and 14-inch arm give it a different silhouette than a standard rail-mount holder. Marine-grade stainless steel and a saltwater feature are listed, and the price is USD 52.70. One limitation: mounting is flush style, so you'll need a suitable flat surface; there's no clamp or rail attachment. If your boat lacks solid deck or gunwale areas for flush mounting, this won't fit the same way.
2X Marine 316 Stainless Steel Rod Holder for 1-1/4"-2" Rail Mount

This version's selling point is the rail mount: it is listed to fit rails from 1-1/4" to 2", with a clamp made of 316 stainless steel and a tube of 304 stainless steel. It also shows deck mount, side mount, adjustable, and removable, which makes it a flexible option for different positions. The listed price is USD 53.93. The tradeoff: the arm isn't as long as the outrigger holder's, and the listed tube length is 10 inches. If you don't have compatible rails, you'd need to look at a flush-mount holder instead.
Final Choice by Use Case
Choose the Outrigger Holder if you need a flush-mounted, saltwater-rated holder with outrigger arms. Choose the Rail Mount Rod Holder if you want a clamp-on, adjustable holder for existing rails 1-1/4" to 2". Both are stainless steel and close in price, so let your boat's mounting points decide.
