Renderer - which has best material library

Hi,

'The most important feature I need from a renderer is a high quality, vast material library. I’m deciding which render plugin to buy.

I’m doing interior architectural renders. I would like access to a material library that is well organised with a huge variety of common materials used in interior design - floor tiles, wall tiles, carpet, marble, stone, concrete and so forth.

I checked out, for instance, Arion, but it only shows about 5 fabric materials on their website. Brazil only seems to come with about 50 materials in total. Likewise for Thea.

Maxwell lists 4000 community materials. Are they any goods? Are they well organised? (and can I navigate the library inside Rhino?)

Vray has their library locked away only to registered users. Can anyone tell me what the size and quality of the library is?

Octane also locks away their library. Can anyone tell me what its like?

I’m leaning towards Maxwell at the moment.

Are there any well integrated renderers that I’ve missed that have a good material library?

I didn't find the right solution from the Internet.
