I've never thought about fonts in coding environments before; you guys must be very experienced if you're thinking of stuff like that.
This is what my editor(Kate) looks like, is this a good font or a bad font? http://i.imgur.com/QtP1csu.jpg

It's not experience, so much as accomodating the repetetivity of software development. Just like getting a better chair or a more comfortable keyboard, one day you find a font that strains your eyes and brain less than the last one, and you switch, and your eyes last longer.
Speaking of which, my absolute first reaction after I loaded that screenshot was "ouch, blur!" - to me, the combination of font, color scheme and antialiasing is making the text quite hard to read. Now, your eyes might be good enough to counteract that, and your screen might be lit differently from mine perhaps as well, making this reaction moot. On the other hand, if you look at some of the sharper screenshots in this thread (curl -s https://news.ycombinator.com/item?id=10140728 | grep -o '<a href="https\?://[^"]\+"' | sed $'s/^.\{9\}//;s/.$//;s/\//\//g;/imgur\|png/s/[^$]\+/\033[7m&\033[0m/'), and your eyes go "...oooh.", then you might be blind to the blurriness of your font. You might adjust this by changing the font, your editor color scheme, or learning about FreeType (ahaha) and how to adjust hinting.
All of this is just technical blathering though; I'm not questioning your choice of font for the choice's sake, or criticising it. I'm just saying, in case you don't realize, I thought it was blurry with my eyes, on my system. :P
As for actually going about making changes and adjustments, this is usually done in the traditional manner - spending an afternoon avoiding the todo list and for example getting horribly distracted with color scheme designers or font comparison utilities or text editor build systems... ;)
I use Liberation Mono everywhere. You might want to give Oxygen-Mono a shot just for kicks since its the "kde" font, but having used both I still like my Liberation.
