Verdict
The clearest difference is review sentiment: GlowWords at 100% against FBReader's 52%. GlowWords also leads on rating (5.0 vs 3.7). FBReader's advantage is ads (none vs shown) and ratings volume (129 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
