Is the Ergotron LX worth paying more than the Fully Jarvis?

The Ergotron LX's typing stability is noticeably better, and the four-point tension system holds position more precisely over time. The price premium is justified if you type on the same desk as the monitor and want a stable screen. If you primarily need height adjustment convenience and stability is secondary, the Fully Jarvis gas spring is a genuine advantage.

Which has better height range, Ergotron LX or Fully Jarvis?

The Fully Jarvis has a slightly larger height adjustment range. More importantly, gas spring adjustment (Jarvis) is effortless and one-handed. Ergotron's spring tension requires deliberate repositioning with slight force. For users who adjust height multiple times per day, the Jarvis is more convenient.
