The only reason I can see for a mod maker to recommend using a certain brand of battery is probably the same reason Chevy recommends using a Delco battery and Ford recommends using a Motorcraft, there is probably some kind of Corporate connection. I use mostly Kanger mods, and the instructions say to use a suitable 18650 30A battery, I use LG HG2 batteries that are rated at 20A, continuous. Kanger doesn't say 30A continuous or pulse. (I haven't blown myself up yet) The brand of battery doesn't matter as much as the quality of the battery, Samsung, LG, and Sony all make quality batteries.
