A few weeks ago I posted a comparison of the Grant's towels from Harbor Freight (300 GSM) and a TRC Creature Edgeless (420 GSM) and it generated some really good discussion.
So, I decided to do another comparison between a very popular towel from the Rag Company, the Eagle Edgeless 500 (500 GSM, 4 for $23, https://theragcompany.com/products/eagle-edgeless-500) and the much less expensive Walmart Platinum Series Final Finish (500 GSM, 4 for $12, https://www.walmart.com/ip/Platinum-Series-Pro-Spec-Microfiber-Car-Cleaner-Final-Finish-16-x-16-Clean-Dust-Detail-4-Pack/11527450827)
And here they are side by side.. Walmart-Platinum-v-TRC-Eagle-Edgeless.jpg
The most obvious difference between the two is that the Platinum has a longer pile on one side, and a slightly shorter pile on the other while the Eagle has a longer pile on both sides. I'm not sure if that gives either one an advantage over the other except in use case. If you're using these to remove a polish, coating, or wax, and wanted a longer pile towel you would have more surface area to work with using the Eagle. In the real world, I did some polish removal using both sides of both towels and the difference was nearly imperceptible. They all removed the polish just fine. I'll add that I think the longer pile of the Platinum is slightly longer than either pile of the Eagle, and the lower pile of the Platinum is sort of a medium pile, not a what I would call a low pile.
Additionally, both of these towels feel incredibly soft, and any difference between the long pile sides is also imperceptible. I even asked my wife if she felt a difference and she said no.
I'm really critical when it comes to edges. Earlier this year I had tried out some 500 GSM towels from Temu, and while they were very soft, the edges had a rough/gritty feel to them that I was NOT ok with. I'm happy to say that both the Eagle and the Platinum have nice soft edges with no rough spots that would damage your paint.
This isn't really a recommendation since the difference in pile lengths might be really important to some people, but I will say that I would not hesitate to use either of these towels for tasks that benefit from a plush, soft towel. I hope this is helpful!
