All I can tell you is that I am satisfied with my Lutron dimmer. Oh, one piece of advice - not all LED lights are compatible with all dimmers. If you know the brand/style of your lights, you can check the website of the dimmer brand to see if they are compatible with the dimmer you are considering. A page like this one from Lutron

Lutron LED+ dimmers are the best. If you just need a simple dimmer with a physical on/off switch, consider the Diva or Skylark. For more features but without a physical switch, the Maestro is the ticket.

For 3- or 4-way circuits, read the installation instructions before buying anything.
