V-bit guide.

60-degree bit is best if using a program like V-carve Pro.
They are rare and expensive. 90 deg bits are more commonly available and cheaper but not as good for CNC V-Carving. 90 deg bits are actually designed for manual 45 deg edge chamfering or v-grooving.
Roland,
The smaller the angle, the more detail you can get. I have 30, 45, 60 and 90 degree v bits in my arsenal. Smaller projects with a lot of detail will usually get a 30 degree bit, average size signs get a 60 degree mostly, and big projects, or signs with large text will get a 60 or 90 degree bit.
Depth of cut for a v carve project is calculated by how deep the bit has to go to fit between the lines, unless you set a flat depth. A 90 degree bit will cut much shallower than a smaller bit on the same project

I downloaded this somewhere. It shows different depth to width info.

Here's a couple of charts I drew up a couple of years ago. I don't know if this is what you're needing or not:

I use everything from 15º to 120º on my CNC. I usually prefer the 60º over the 90º for signs, because I can get a deeper cut. When I need a lot of detail or have small text, I'll use the 45º. I have found there is little difference in price between the 60º and 90º bits, and suggest you acquire as many different V angles as you can over time because there is no "one size fits all," and the bit you need depends on the design you are carving.

Thank y'all for the fantastic information. I've been playing with a 90 deg bit and discovered that without proper gapping or kerning the letters can get a little squished-in the deeper you go. I'm gonna play with a 60 next. Got it off Amazon for 8 bucks. The charts are awesome!
