Darrin,
I sampled an AT4050 and my God, amazing true clean (just about flat) sound. It is accurate yet has a great clean bass response below 80hz which is what I want. Boost around the 11khz range for a more sparkly high. I read an article which stated that 2 companies which are standing out for NOT producing junk that sounds good in a vocal booth (because of eq boosting and lowering, geared more towards uneducated home studios) were SHURE and Audio Technica. So when comparing the KSM44 and AT4050, there is literally almost no difference and practical recording sound. There are slight differences in the 80Hz and below, and the 6kHz and above but they are almost non detectable by ear. The AT4050 is roughly $100-$200 cheaper than the KSM44 but the KSM44 has a sturdy shock mount (which can be necessay when dealing with some bands) and an additional roll off which appeals to me since it is at the 6kHz range. If I was going for pure sound, I would go for the AT4050. Since i'm considering some factors which I just mentioned, I will be going for the KSM44 as of now.
So for a large diaphragm condenser microphone geared towards:
clear male vocals (with clean bass below 100hz and sparkling highs around 12kHz) and all around useful mic for instruments (surprisingly includes miking bass amps, guitar amps, and even bass kick [with pad turned ON of course] as long as dB's are below 149 with the pad on and below 125 with pad off [there really isn't anything I can think of that you can't record without turning the volume down to below 149dB], I would go for the KSM44.
