Where I am, cheap rice and cheap pasta are about the same - something around $1/pound, $2/kg. Ramen is decidedly not cheap at $3-4/pound. Even the 'fancy' pasta brands are only $2-2.50/pound.
Rice. At least there's healthy rice alternatives, there's a lot of dishes that can be done with rice. Far more than what fewer options there are for ramen.
Ramen can come into all sorts of flavors but the flavors are only supported by the packets with them or the sauce packets with them. In general, they're just generally unhealthy and you can do so little with them.
