They improved the UI from the mess it used to be to tolerable but the main issue that happened before the Crunchyroll Funimation merger was the Crunchyroll originals

They were either full shit (High Guardian spice) or had a great set up but they rushed the story so became mediocre (God of High-school)

When money isn't going more to Japanese studios but to these originals, it's leaves a bad taste. After the Sony acquisition, they dropped Funimation and merged it all under Crunchyroll (which surprised many but I predicted it as Crunchyroll less tainted due to Vic drama). They ported over all of Funimations library but lost streaming rights to a few.

Out of the 'legal' options, they have the bigger library and are better at releasing shit than Netflix and Disney but to watch everything you'll need to sail the high seas a bit. It's a shame because Sony have the perfect opportunity to dominate if they did a discount for PS+ members, had an adult section where you just need a seperate password for uncensored anime and maybe link directly to studio's merchandise to make it more worth to be with them. Right now they are resting on having the bigger library.
