Kobo plus books

I am debating getting a kobo. I signed up for a free trial of kobo plus to see what books they had to offer, and I only see a few I recognize. I normally read thriller and romance, but am open to whatever. What books have you liked on kobo plus?

I already have a Kindle so I have KU and libby. I'm a huge reader and love the design and function of the kobo libra color, but if all I do is use it for library books then I'm not sure it's worth the $200+. I want to get some use out of kobo plus if I get one, but I'm not sure if it's worth it or not.
