Obviously size is important, you have to get it close, but I feel the absolute most important thing is to get the diaper positioned perfectly around the leg openings where they meet your body. I know this too sounds obvious, but until I checked the fit in that critical area I was getting leaks too, even with premium diapers. I thought I was getting my diaper on properly but the fit check revealed otherwise. Once I started doing a final "fit check", which meant running my finger all along the elastic gathers and making sure they were snuggly against my legs, and making sure there was no excess material in the way, the leaks went totally away.
There is a lot of fastidious fitting around getting a diaper on. It's more than just taping up. There's fanning out the diaper, folding it to get the crease right (kinda like getting the crease on a ballcap right), tensioning the leg openings against your pubic bone (not your thighs), positioning the tapes consistently (diapers with a print on the landing zone really helps which is why I love the TotalDry brand), and rolling all excess material in so that the fit is tight around your thighs, especially.
Granted, I guess I'm....lucky?.... that I have a constant trickle in addition to large, urgent voids. I've found that I might as well just try to use the diaper when I can have a smaller void. Leaks are borne of large voids and ill-fitting diapers. When I haven't been hydrating properly, I actually have no leaks because the constant drain is easily handled by my current setup. YMMV.
