Any mic will capture a vocal source unless it's broken......
Whether it's the RIGHT mic for that particular voice in that particular environment through that particular electronic chain is anyone's best guess.
A home recordist who primarily records only them selves in their own space SHOULD invest the time researching which mic is going to be the best for their individual usage and not worry at all about what everyone else is using for their projects. I have always found the answer to this, for an individual, to be surprising as to what actually works and gives the artist/recordists their best "bang for the buck".
I could give you a list of the vocal mics (of course they are all good on lots of things) that I primarily choose for use in my studio, but I record a bunch of different voices and as such require a mic locker that reflects this. You require only one mic which, BTW, you already have a decent model of. Perhaps it's not the mic that is the problem but rather the "newbie status" you claim and this is what's keeping you from getting the tracks where you want them.
Over the 40 years or so I've been putting mics up for folks to sing and play into, I haven't found very many instances where buying something cured the lack of knowledge about the problem.
But I do understand having choices in your mic locker can be beneficial to creativity. Might be one of the reasons I have accumulated the number I have. One thing I HAVE learned is to know what each style of mic does, how it's polar patterns are shaped and what sort of frequency response is within these shapes, what the electronics of mic may mean to sensitivity and frequency response, and how aim the damn things........
Before I go, I want to tell you about the "hidden gems" that are out there just waiting to go home with someone....A previous poster suggested the Studio Projects T-3. I agree. You don't hear much about them these days but 10-15 years back these were the home recordist's best friends. Still are if you can find a clean low milage one from that era. Groove Tubes mics. Specifically any of the GT series from the early to mid 2000's. Very good mics and built like trucks. ADK mics. Larry has built so many different models over the years that it's hard to choose. But they are all real good. Any 40 series Audio Technicas. You could equip a whole studio with a bunch of these. The Shure LDC's. KSM's. KSM44 is around the same retail as an AKG 414 and will ALWAYS be a better mic for vocal captures in most cases.
So what do I use? I have a Cathedral Pipes U67 clone, an original U87, Two ADK TT tubes customized ...one to a Neumann U47 and one to a Telefunken ELA M 251, AKG C414 EB, Cathedral Pipes Seville Ribbon, Royer R 101 etc etc
