Big blocks
Holders want it more than users.
Big blocks lower mining fees while making running node more expensive. Holders rarely run a node.
It's the other way round.
Holders are ok with small blocks because of the "anti-censorship" that comes with
the ability to run a full node with limited resources, which is made possible by
the smaller amount of transactions in smaller blocks.
Users - i.e. people who would like to actually
buy things with bitcoin - would benefit
from bigger blocks, smaller transaction fees and faster processing of orders.
