I might not qualify as "experienced" with the 3k or 4k...
I'd prefer a 2000 with a Royer mod.
Remember its not just the mic but the engineer as well. Also, the application of your mic will be something to consider. Are you recording rappers, singers, or will you use for instruments as well? There isn't a all in one mic but there are some that are very versatile. If you can hold off and save up there are a few better options for a few hundred more.
If you can't wait I'd say buy it if you can get it from a local store that has a 30day return policy. Play around with it and see if you like it.
First adjust your gain staging to your liking.
Then develop and apply an eq template to compensate for its response curve (adds clarity).
Lastly, the mic is not the only consideration as it isn't the only component in your chain. There are some pre's that emulate more expensive one's for a quarter of the cost. A excellent pre with a okay mic can sound really good... maybe not the best to an audiophile but general public couldn't tell the difference.
