While browsing for film reviews, a video popped up from YouTube by Denae and Andrew with reviews for every B&W film available in North America in ISO 100 and ISO 400 speeds. The YouTuber also has a review of a number of developers and a C41-process colour film guide.
His reviews include time stamps to find the relevant parts of each review, should you wish to skip ahead or rewind to review his methodology and results.
He has strong opinions and does not hold them back in the conclusions. For example, he pans Fomapan Classic 100 for having uneven, unpredictable grain. While this look may be disappointing depending on what one wants out of a photograph, it does lend a classic look to the finished prints.
There are lots of comparison photos and closeups of grain to see. He has organized the film types by a signifying letter in each photo. Note the letter on the pics you like, then compare to the list of films that correspond to the letters. You may be surprised.
Check out a list of his film reviews and guides here.
