My daughter reads a lot of books checked out via overdrive on her kobo (in Canada), though the search feature on the kobo itself is kind of garbage. We have better luck doing a search with the Libby app on a phone, checking it out, then syncing the kobo.

I use a Kindle myself (purchased on one of the good sales for roughly half price), though primarily via epub files transferred to the Kindle using Calibre. It's a busy UI, but it does work well and has lots of features. Pretty good as an archive of your ebook library.
