Out of universal foams, I feel that the Olives have the best isolation/comfort/SQ/durability balance out of any other options. With the right size, they're comfortable, don't itch, isolate really well and give a nice warm sound. And quite reusable as well.
Yellow foams are great SQ wise (IMO best out of all universal tips), seal alright, but they have potential to itch the hell out of your ears and gets dirty/lose their expanding abilities quite quickly.
Triple/Double flanges are obviously quite durable/reusable, have good SQ, and isolate very well, but I feel that they are the least comfortable out of any of the options. They can hurt your ears and also itch the hell out of them.
Complys are probably the most comfortable and have great SQ, but is one of the least durable and get dirty VERY quickly. They also don't isolate as well as above three.
Silicons are the worst, IMO. They sound alright and are durable, but lose their seal easily and can be uncomfortable pressure wise and itch a lot. Isolation is meh.
