KSM32

Consider picking up a KSM32, won't break the bank and I use it for almost 100% of acoustic guitar tracking.

In my opinion, Shure SM58 sounds better than the mics you listed. I know this is controversial, but the thing about condenser mics...is that you need to spend minimum $800 to sound decent. Rode NT1, AT2020 and P220 are all harsh sounding and sound...cheap. Try considering Roswell K87 or Shure KSM32 if you really want a condenser and not break the bank. Also kind of off topic, but make sure you put yourself right in front of mic (like almost kissing the mic) to get as little background noise as possible! Proximity effect can be dealt fairly easily than your room reverb (and noise).

Shure KSM/32. It’s got the fullness and much of the character of a U87 but with a smoother and sweeter high end. And the low end rolloff switch is great for reducing proximity effect without coloring the vocal frequency range. It’s also relatively affordable - not cheap but not too expensive.

The OC818 is multipattern, the OC18 is the cardioid version. The OC16 has a mid-forward voicing, better suited for guitar cabs and drums and such. I picked up a Lewitt 540S a few months ago and it's quickly become my go-to LDC. Shure KSM32 is also a safe bet. Audio-Technica AT4047/SV is also fantastic but they're a bit hard to find. There's a bit of harmonic richness with the transformer that works really well on female vocals, but not the best choice if you want a super clean, modern sound.

KSM32. I really wanted to like it but I just don’t. It’s more harsh sounding than I imagined given its reputation for being a smooth sounding mic. My Earthworks SR117 sounds much smoother and very easy to get it sit in a mix.
