Octane is by far the most expensive option, the price point of the software alone rules out many hobbyists and it also requires a powerful GPU to get quick results and the texture size is limited to the GPU RAM capacity, GPU's upgrades can also necessitate a PSU upgrade to power the card(s). For a professional it may be a great production pipeline but the cost made it highly impractical for my use.

I rendered this using Reality into LuxRender on a dual xeon 2.26 GHz. Mac that's over 4 year old, these are the results after after one hour and sixteen. minutes
