I've tested others and none compare
I've gone through many other brands and models of 4 in 1 esc's and this one is hands down the most durable and reliable. I've only had one go bad on me after running about 15 packs 5 days a week for the last 4 months. That's a good rate compared to what I've experienced with other 35 amp 4-in-1's. I'm running the 2600 kv f40 pros (older ones with silver winding).
