By windows 7, you mean the emulated windows 7 rendering in infinality? I am still referring to native cleartype, not infinality's window 7 emulation which is better than cleartype. I use custom options which look better than both of those IMO. One of them is too blurry, the other is way too sharp and pixelated. The glyphs are also not aligned correctly in either one. I'm guessing you haven't taken the time to configure it.
You do realize that intel, IBM, AMD, Samsung etc all have full time linux devs, right? Each to their own i guess. I am far more productive in vim than in any other editor. the learning curve is steep, but it was worth it for me in the end.
