Ducvet is, of course, correct and is based on years of experience.
I just went through this myself, I'll add some stuff I found from doing it for the first time and approaching it like you. I picked up a Ducabike roller-hub slipper with an aluminum basket and pressure plate for very little money (less than the cost of just buying the Ducabike basket new!) with low mileage usage, but it needed a clutch pack. Thus my search for data began.
As you know, there are three types of basket material - Steel, Aluminum, and Hybrid. Aluminum baskets get aluminum plates, steel baskets and baskets with steel inserts get steel plates. Otherwise the material hardness is disparate enough that you get accelerated wear on one or the other. Usually it's someone installing steel friction plates in an aluminum basket and wearing grooves in the basket. You can extend the life of a basket like this by re-stacking the plates and swapping the convex plate to the other end of the stack - this offsets the pack by one plate width to get the frictions aligned with the non-worn portion of the drum. You might extend the life of the basket by about 25% by doing this and it will definitely make the whole thing quieter.
The OEM hub and steel drive plates showed no significant signs of wear when I took mine out. Stick with the OEM hub unless you have a specific need to change. Your replacement kit should come with steel drive plates, usually they are OEM drive plates.
So it's a matter of matching plate backer to the basket, and friction material you choose. Unless you have a specific need for sintered (slipper clutch, racing application, etc) get the organic material.
In my case, aluminum basket with a slipper hub, I picked up a set of sintered aluminum plates, Ducabike makes them and they were priced lower than some of the other brands out there when I ordered them from Bellisimoto. I don't know that they are better or worse than any other, but they were specified for my clutch by the manufacturer. Haven't felt any chatter on them yet, they felt just like normal. Some people swear by Barnett, others swear off Barnett before you even say their name. Surflex is another brand to look at, and others.
Really, you can't go wrong with OEM plates, and I believe you can get them in steel or aluminum depending on the part number. Ask at your local parts counter, or if they aren't able to help (as some dealers seem to be) try calling the Motocorsa parts counter in Portland, Oregon - Marc and Miles have always been excellent to me.

It's Italian. If I can get it to start, it'll win.
