You can't determine a synth's value based on it's components, or it's sounds. A PC with completely free plugins and VST will be always be much more customisable and "powerful" than any hardware device, and have better sound, too. That's not what you're paying for.
You're paying for UX that creates the pit of success for your music-making process.
You pay for the fact that you use knobs, not mouse — although you would be able to draw an infinitely detailed automation with it. You pay for the limited choices you have, and where these limitations lead you. You pay for the touch & feel. You pay for purely subjective, aesthetic factors, like look and smell — because music-making is a completely subjective, intuitive process and your psychological state is more important for it having a Turing-complete LFO system.
I like OP-1 and I like Octatrack, but there's just no way you could have any objective "measurement" for which one is better of has better value — because any value that these devices have is subjective. If you want to decide which one to buy, forget everything about specs, and just spend an hour or two playing with them, feeling them with your hands while you make music.
