Although aesthetically, Reeder might have the slight advantage over Readkit (even with the Incorporation theme), it really lacks a killer feature that Readkit provides. Full text search within feed content. Yep, a feature as simple as search is the make-or-break feature that I’ve been looking for. Readkit has it, so it wins in my books.
That said, it is a bit slow on my machine - Core i7 4.0GHz with 24GB RAM and 1TB SSD. Not quite sure why that is the case. I have another machine - a Core 2 Duo 3.06GHz with 4GB RAM and a spinner, and the performance is the same as the core i7. So, yeah the problem lies with the app.
