It doesn't. Fluke is more expensive and higher quality. This will probably be good enough for 99% of people though. I'm a commercial electrician and have a similar Klein Meter and it's all I need. I'd buy a fluke if I worked on a lot of high voltage or sensitive/expensive equipment routinely where a small mistake or variance could cost big $$$$.

The meters you're comparing are different so just depends on what features are desired.

It comes with FCI Tester and Line and Splitter. But it is not TRMS and no Temperature.
Which one to get?
