They're all about the same, best way to shop ST trailer tires is on price. None are made in US anymore, they are all made in China, so the brand really doesn't matter. Weigh your trailer and make sure you're not overloading the tires. Get 'em balanced and they will last longer.
Many here have reported Maxxis as good brand, but limited dealer network so limited availability in many regions and higher priced than most.
