Honestly, there's no single modular desk system that wins for every office.
For a small team of 2–4 people, face-to-face modular workstations work great. Desks connect together, add a screen in the middle, cables get tucked away neatly — nothing complicated about it.
For an open office with dozens of people, I'd lean toward a benching system instead. You can add workstations row by row — start with 20 people, and just keep extending it as the team grows.
Some offices care more about quiet and personal space, in which case office cubicles with taller screens and built-in storage make more sense. They're not as "open" as a workstation setup, but people calling clients or handling paperwork will be a lot more comfortable.
So when I'm picking a modular desk system, I usually start with a few practical questions: How many people right now, and is that headcount growing? Where do the cables need to run? Does everyone need their own storage? Is the office layout likely to change down the road?
Once those are answered, the right system usually becomes pretty obvious.
The best modular desk system isn't necessarily the one with the most features — it's the one that lets you add a few more desks later without having to buy out the whole office again.
