I've tried LR several times and dislike it despite repeated attempts ...I just don't like using it.
In fact, the more I used it, the more I appreciated using Bridge and Photoshop for my relatively low volume 'big pictures' workflow.
I just don't like the whole catalog concept, which is a pretty fundamental sticking point. I'm not convinced either with a non destructive editing approach. In fact I ended up using LR as a glorified RAW converter (which it does well) since my workflow then goes right into PS.
I do quite a lot of large prints (I've just finished a lengthy pre-release review of Epson's new P-800 printer) so the print workflow in LR doesn't cut it either, nor do I use mobile devices (I rarely take a mobile phone with me when out) or need web galleries. I've already tried LR6 and find no use for faces (I don't do people stuff), HDR or its stitching, and LR Mobile still mystifies me as to what I'd ever do with it.
I'm very much not in the LR target market (but still heartily recommend it to people to try).
