Nothing. It would be useless to shell out more money to get a higher spec mic.
In an untreated room of an usual city apartment you must use close miking to win the noises of the house & traffic and the very uneven room reverberation (=resonances). I guess you have a hobbyist grade mic preamp, so even a fully silent room and a zero self noise mic wouldn't allow clean recordings of gentle human speech from say 1 meter distance. So the a little high self noise(=18dBA in manufacturer's datasheet) isn't any problem. With close miking you'll get easily at least 75dBA level at the mic. You'll use editing, noise gating, gain riding or adaptive noise cancellation to make silent periods of the recorded track fully silent.
Noticeable bass roll-off at 100 Hz is not a problem. You cannot generate any useful deep bass sounds which fill your room evenly. The bass boost caused by close miking (=the proximity effect of cardioid mics) is unpredictable. In theory it and some lucky eq could together help you to record deep sub-100Hz bass with that mic, but you must have some incredible luck if it stays stable through a 3 minute song, not only for few notes here and there. And in any case those boosted bass sounds would start and decay slowly.
I guess any decent deep bass in your studio will come to your recordings directly along wires from musical instruments or as samples.
BTW. It's well possible that there's some mics which make just the right sound for a certain music or playing style. For ex. blues harmonica players expect certain harshness and distortion (it's the amp, too, not only the mic!). Even a vocalist may want something which colorizes just his voice as he likes.
