G602/4 gang! I picked up a Razer Naga Pro to play around with since it also has a 6 button side panel that is hot-swappable for a 2 or 12 button configuration too. I think the Logitech mice are more ergonomic (but I’ve also been using the G602/4 for years), and I hate the Razer Synapse software. Being able to switch to a 12 button panel for some games is useful, but I find 6 buttons to be the sweet spot for general computing. I think the Naga Pro is the closest option for the time being unless Logitech decides to introduce a new model.
