I have UAD's Ocean Way Studio plugin which is very similar to IK Sunset Studios.
I prefer Sunset. It's not only the UI I like better, but the sound is there. Like someone said in a previous post, it does sound like a live room.
I didn't get it when it first came out, so I didn't pay full price. I got it with some kind of deal I don't even remember. But when I used it alongside/compared it to UAD Ocean Way, I realized I spent my money well.
$35 is no-brainer.
