I don't do much gaming but do a LOT of typing. Would you still recommend the G613 if I don't care much for the "gaming" features or programmable buttons?
I am indeed! It's really nice to type in it! I love it! It is very modest-looking compared to other gaming keyboards (NO RGB WOOOT!), has decent media controls (no volume dial, but volume buttons) and programmable macro buttons that I ended up using for Photoshop, Lightroom, Word and Excel. Supports Bluetooth too, and the battery is superb! still running their first batteries and still running strong! I have nothing but praise for this keyboard! I use it for both my desktop and my HTPC when I need to troubleshoot stuff in it! As for the N-keyrollover, I have not encountered any problems with it in Overwatch and Quake Champions, however I have not gone lengths of testing it thoroughly for that purpose.
The downside is that it's expensive (at 129 CAD). I don't think I'll get another daily driver keyboard (like the Kira, but I would get it for collecting purposes). Another potential downside is that it uses Logitech's custom Omron/Romer-G switches, those can throw off some people too. It is on the quiet side of mechanical switches, but it is not "quiet". I would recommend trying this keyboard at a store first before buying it!
PS: It seems that some batches were shipped with poor quality AA batteries that will make the keyboard glitch - if this happens, just get another pair of batteries, and that should resolve this problem.
Edit: Wxcel to Excel, heh
