Instant ramen is to fresh, as Sanka is to Peets.
In other words, there’s no comparison.
As goboy recommends, try a ramen shop in your local Little Tokyo or Japantown if you get a chance.
Yes, other Asian countries have noodle-in-soup dishes (pho in Vietnam is a good example), you haven’t tried REAL ramen/rahmen until you’ve tried the fresh stuff in a Japanese ramen shop.
BTW the best ode to ramen can be found in Juzo Itami’s 1986 classic, Tampopo, a great movie about the quest for the perfect bowl of ramen. It’s hilarious at times (the non-sequiter segues related to foodstuffs is particularly riotous) but most of all, makes you wish you were sitting with a big bowl of noodles. Rent this if you can. It’s one of my favorite movies.
