Best potato for potato soup?

[Worth1]

I would like to knoiw what many of you would think the best potato would be.

I so fasr have liked what the store calls dutch creamers oi Russian fingerlings.
Russets are out as well as the red potatoes they sell at the store.
You know the red ones they call Irish potatoes.
In reality the Irish potato was they called white lumper or so I have read.

What I want is a white or yellow potato that doesn't fall apart but stays creamy.
