Crunchyroll do have a large back catalogue for anime that has aired this decade, and one that is very diverse at that. Obviously things go in and out of license like any other streaming service but if it's volume of stuff to watch I think Crunchy delivers on value. Now if there's something specific you are looking for OP or the old classics, Netflix and/or HI-DIVE might suit you better.
Of course the streaming anime market is much more competitive now and whichever service you go for you're not going to get everything (unless you have enough money to subscribe to Crunchy, HI-DIVE, Netflix and Amazon all at once). But for keeping up with a lot of shows that fit my tastes and its back catalogue Crunchy has been worth it for the few years I've been a subscriber.
However the elephant in the room is the level of service which has consistently been patchy. You'll get a spell of good service then there'll be a longer dry spell where you struggle or can't watch anything at all (the situation we seem to be in recently).
So I'd say yes it's worth it for the content, but beware of their patchy level of service. It would be a good idea though to browse around the different services and find out which one fits your viewing habits best.
