These days, you will find people who have "the religion" on either side of the meter question. As with all "religious" questions, the best answer is individual choice. It's kind of like the force--there is a light (meter) side and a dark side .
For film, a meter was essential using studio strobes. At first with digital, I used my meter because it was what I was used to from film. Soon enough, I wouldn't bother to dig out the meter because I was close enough to dial it in. And for most uses, this is plenty close.
But I've been converting back to the other side, especially when I'm not tethered and just have the back of the camera to go by. Sure, it can all be adjusted in post within reasonable bounds (i.e. if it looks right on the LCD and camera histogram, it isn't very far off already).
A nagging sense that really precise exposure does improve the quality for prints, especially if you are pushing up the size, has been taking over.
I have a meter I trust, a Gossen Luna Star F. But a Sekonic L 758 became available used and I gave in, mostly for the convenient spot flash meter option, although I appreciate the complex calibration options.
So I seem to be going back to the church of my younger days...
If you decide you want to try it, there are plenty of good, used flash meters on the market, so you don't have to invest so much to try it out.
