We are heavy users of both Graylog2 and Logstash and they both shine at different things at the moment. In an enterprise context with lots and lots of logs Graylog2 is making the process of segregating access to certain logs very,very easy. It's interface is a lot less "bling bling" than Kibana but much easier to use for a certain type of users. Logstash is still king for parsing logs into structured events (and we use it a LOT - our current config file is ~2.5k lines) but we had issues with stability and loosing messages (crashes due to character issues, etc). The core of Graylog2 rocks - it's stable and very performant (we are pushing 30k+ msgs/s over a single node with room to spare) and the support we have received from the Graylog2 team has been nothing but awesome. I am confident that they will catch up with Kibana (in terms of visualisations) very, very quickly.
