I am a fan of the Musgrave Tennessee Reds. Dark graphic that doesn't require a lot of pressure, and a fine looking pencil. Be warned, however: Musgrave hexagonal pencils have a very crisp shape, and some people find them uncomfortable. The Musgrave 600 News is a unique pencil (and has a round barrel) that lays down a heavy, dark line.

I picked up a box of Blackwing 602s a few months ago (thanks to a gift card). They are more comfortable in the hand than the Musgraves, but I prefer the graphite in the Tennessee Reds. I may try one of the darker/softer Blackwing models in the future.

As for review sites, I've really found the Polar Pencil Pusher to be helpful (https://polarpencilpusher.home.blog/).
