Kontakt 8 is Native Instruments' software sampler platform for hosting and building virtual instruments, available as a plugin or standalone app.
Reaktor 6 is Native Instruments' modular sound studio for building and playing custom synths, samplers, effects, and sequencers.
Editorial analysis
Kontakt 8 and Reaktor 6 are both Native Instruments platforms rather than single instruments, which is why buyers weigh them against each other. But they sit at opposite ends of sound creation: Kontakt is a sampler that plays back and shapes recorded audio, while Reaktor is a modular workshop for synthesizing sounds from raw DSP. They rarely compete for the same job, and choosing wrongly means owning a tool that will not do what you actually need.
Decisive signal
The deciding split is sampling versus synthesis, and it determines everything downstream. Kontakt's whole reason to exist is hosting recorded material: the commercial library industry builds on it, so an orchestral, guitar, or vintage-keys collection almost always ships as a Kontakt instrument that just loads and plays. Reaktor holds no such library ecosystem; instead its Primary and Core levels let you patch and even compile custom oscillators, filters, and sequencers that exist nowhere else. Put simply, Kontakt gives you the world's sampled sounds through one universal format, and Reaktor gives you a blank canvas to invent sounds no sample can capture. One is about access, the other about creation.

Choose Kontakt 8 if you buy sample libraries and need the platform that runs nearly all of them, from cinematic strings to sampled synths.

Choose Reaktor 6 if you want to build custom synths, samplers, and sequencers from scratch and treat open-ended sound design as craft rather than preset-hunting.
Open plugin file →Buying verdict
For most producers who buy and load sample libraries, Kontakt 8 is close to unavoidable and its 8.7 score reflects that near-monopoly on third-party support, even at $299. Reaktor 6 scores 8.4 and costs $199, and that lower price is honest value for a tool with a far narrower audience: people who treat sound design as building, not browsing. Neither is a better plugin in the abstract, but Kontakt wins the practical default because more real sessions need a library host than need a modular DSP lab.

Quick reference
Kontakt 8 is the gentler entry, because most people use it simply to load ready-made libraries and play them, and the free Kontakt 8 Player handles that with no cost. Reaktor 6 has a steep learning curve since building a patch from a blank canvas is a project, though its Blocks layer and huge free User Library soften the start. If you just want sounds fast, begin with Kontakt.
They are priced for different value. Reaktor's $199 is fair for anyone who designs instruments and effects, but it is overkill if you only want polished presets quickly. Kontakt's $299 buys access to the industry-standard library format and a 40 GB Factory Library 2, which most producers will use far more often than a modular build environment.
Many sound designers do own both, because they cover complementary ground rather than overlapping. Kontakt handles sampled and licensed libraries, while Reaktor generates original synthesized textures you cannot buy off the shelf. Both are also bundled together in the higher Komplete tiers, which is often the cheapest way to end up with each.
