Correct, Full Spectrum and Isolate have different properties and benefits. However, which is "better" depends on what the consumer is seeking.
An intelligent strategy that POTN seems to be utilizing is to diversify across the range of CBD products and compounds, apparently from full spectrum, to partial blends, to isolates for a diverse range of products.
That sounds like a very solid idea in terms of increasing broader market appeal.
I just hope they soon expand into more highly blended THC products.
