Choosing a downspout splash block is a small but important part of any roofing and gutter waterproofing project. It usually comes down to matching the product to the number of discharge points you are protecting. These two blocks take different approaches to that job: one is a replacement-style guard, the other is a set designed for extended water flow.
Quick verdict
The Suncast SBR24 Decorative Home Splash Rain Gutter Drain Block Replacement Guard is the pick for a direct replacement job, with a listed price of USD 20.19. The NAACOO 2 Pack Downspout Splash Block, listed at USD 27.99, is the pick when you want the broader coverage of a set. The price spread in this comparison is $7.80.

Where each option wins
The Suncast wins if you want a replacement block with a clear model identifier and a single guard at the end of a downspout. Its strength is simplicity: the model number and UPC tell you exactly what you are looking at. The NAACOO wins if you want a set that covers a wider area and is designed to keep water moving away from the house. The channel-style design is built around directing flow rather than just catching it.
Product notes
Suncast SBR24 Decorative Home Splash Rain Gutter Drain Block Replacement Guard
The useful part of this product is that it is explicitly a replacement-style guard: model SBR24, UPC 0044365019239, and a decorative label that describes the look of the guard. If you are replacing a gutter drain block and want the part identity to be clear before you buy, that is the strength. The limitation is the single-unit format, one block per purchase. It is a practical, no-frills way to handle one downspout outlet.
NAACOO 2 Pack Downspout Splash Block, 24\" Rain Gutter Downspout Extensions/Ex
This product is built around coverage. It comes with two 24-inch blocks in Dark Green, a 15° slope to help water flow away, a ladder-downward design meant to avoid trapping dirt or water, and a PP material described as UV-proof and capable of bearing 500 pounds. You can use the blocks on their own or splice them together, which adds layout flexibility. The trade-off is the Dark Green finish, so it helps if that color works with your exterior setup.
Final choice by use case
If the product needs to match a simple replacement task at your downspout, the Suncast SBR24 is the more direct choice. If the need is for broader runoff coverage across multiple outlets, the NAACOO is the product that scales to that job. Keep the comparison table handy as the final checkpoint.
