It's a good extension for several other browsers, very well maintained and optimized. That said, as of Maxthon 18.104.22.1680, I've found that my ad-blocking needs are well taken care of. Maxthon has spent a great deal of time into optimizing the ABP extension to fit seamlessly into the browser. I'm not saying I wouldn't love to see the developer of uBlock make an extension for Maxthon, but I will say that it's the synchronization of bookmarks and address bar that occasional slows me down. Thus the reason I sometimes temporarily disable the two during heavy browsing sessions. So I'll be happy either way, since with the addition of ABP, Maxthon has become my number one browser once more!
