The best make is a strong one. If it sticks hard to the sides and doesnt bob about, its good.
If the divider is clear and thats not what you want (it can be more stressful, yes), use craft mesh or knitting/crochet mesh found in crafting stores. The plastic kinds are in lots of colors and usually very cheap. Cut them to proper size and it will work wonders.
The trick is the spines the dividers use. Depending on the tank, you can use ones that rely on pressure to hold still or ones that use claps over the sides of the lid. Lipped tanks (with a rim that overhangs) will not work well for this.
Try what you can find locally, and if they do not appear to do as above (unstable, too short too tall, etc), then return them if possible, and try again.
I use the spines and clasps from the American Brand Top Fin. They work very well and the clasps do, too. I replace all of my dividers with plastic mesh canvas.
