I have the Nema23's and I haven't run into a situation where I wanted the 34's or thought I needed them as a Hobby user. I was cutting 1/2" plywood with a 1/4" bit at 120 with a 1/4" pass and had zero issues. I kept increasing the speed to about 140 when I started seeing chattering and backed it off. My opinion, and take it for what it's worth, is the software might come in more handy. I didn't care too much about the speed since I'm using it just for a hobby.
