If you ever wanted to watch live-action Death Note as well as some classic J-Drama, Crucnrhyoll is your pick.
No longer is anime confined to imported DVDs and late-night time blocks on premium cable channels.
Since I don't live in the US I really don't have any other options than Crunchyroll, and I have a standing subscription even when I don't watch anything because of laziness. By hovering over the Shows button on the menu bar, you can sort through the most popular anime, find anime by genre, view all simuldub anime shows, or just look at all shows alphabetically. But I heard recently that Funimation also has a subscription service in a similar fashion, but it also has dubs as well as the simulcasts.
However, Funimation has a huge library of old shows that Crunchyroll doesn't have, and every season there's at least one or two new titles that only Funimation gets and sometimes they're worth their subscription cost.
Whatever void that Crunchyroll can't fill Hulu can fill most of it. Gundam Build fighters aired on Youtube though didn't it? Do you have proven online publishing experience? I don't mind there not being any dubs and they have a large selection of shows I enjoy.
The only downside is that once you're reliant on streaming services, it takes greater dedication to not miss the shows that neither gets. All the latest gaming news, game reviews and trailers.
A friend of mine, however, have paid for Crunchy on and off whenever there are shows he likes to watch, and if you're the kind of person who likes to binge watch it's extremely cost effective to pay for one month and watch the hell out of everything.
What do you like or dislike about either one? You can also have the choice to play your favorite shows offline via Funimation Premium Plus. We put the two side by side to see if there's a clear victor. They have a ton of titles including a ton of titles Funi and CR don't have. It also adds sentimental value and physical representation of a time in your life for a lack of a better way of expressing myself. Funimation and Crunchyroll seem to be the most recommended sites, so I ask what is the difference? Well Funimation has the best VA's, and they are in Texas so they don't have that irritating actor's union crap that prevents the VA's from doing their jobs.
For example, last year, fans wanted the classic remake of Fruits Basket to be on the catalog, and they complied. We are going to compare the two companies and answer the years-long question: who has the best catalog? Everything is automatically organized by the most popular.
But if you want to know more about the anime you picked, the only thing they provide you with is a short description. If you only use the Funimation app, this will catch you off guard.
To add to the other comments, IIRC Crunchyroll has a deeper catalogue of no-longer-airing shows than Funimation, stuff like Space Cobra, Lupin III or Kaiji, and one-off things like Pale Cocoon.
