Which recovery tool is better??

Hi guys,
Which recovery tool is better for reverting back to WP8.1 from W10 mobile preview??
Windows phone recovery tool or Lumia recovery??

Basically the one that works for you.

Windows Phone Recovery Tool covers most of the Windows Phones (including Lumia) and is theoretically the successor to the Lumia recovery. Lumina Recovery obviously only recovers Lumias, but several people have mentioned that Lumia recovery sometimes works when the WPRT doesn't work. My suggestion: use WPRT first, then using Lumina Recovery if you run into any problems.
