This post collects some comments from online sources and seeks to demonstrate those comments when looking at the details of two speeds of Kodak T-MAX films: TMAX 100 vs T-MAX 400. Other than the speed / sensitively of the film, what is the difference? Do those differences show in the results?
Part of my own "return to film" is exploring the different film types. Today's available film types are primarily premium emulsions, shot in premium cameras. For 35mm film, this common "full frame" format dates back to Kodak in 1934. As the popularity of handheld photography grew, along with available cameras, the 35mm format became the most popular photographic film size in the late 1960s. Kodak TMAX is a relatively recent release, dating to 1986.
For the term film 'emulsion', this refers to how the silver halide grains are suspended in a gelatin colloid. Different film types, aka stocks, use different shapes of the silver halide grains, creating different 'looks' in how the film looks in terms of sharpness and the tone of the black and white contrast of the image.

Kodak Professional T-MAX Film is a continuous tone, panchromatic, tabular-grain black and white negative film. T-MAX has a chemical makeup that was revolutionary for its time in the mid 80s. In the 1970s, a tabular grain (T-grain) was created to pack more chemicals onto the surface of the film emulsion, a critical need for color photography. Kodak was the first to use the same technology with black and white film, creating T-MAX. These tabular crystals gave T-MAX a sharper look and more contrast than any other black and white film then on the market. Current T-grain films include Ilford Delta, Fuji Acros, and Kodak T-MAX at 100, 400, and 3200.
As I scanned my Lightroom catalog for T-MAX examples, many of my favorite images were captured on T-MAX. This was an odd realization given how much I've been investigating and shooting other film types. All three of these current T-grain options (Delta, Acros, T-MAX) are my preferred films for sharpness and contrast.

B&W Water lily T-MAX is know for protecting highlights and providing a smoother transition to shadows. These examples demonstrate a few situation, including indoor light, outdoors sunlight and overcast snowstorms.

Graceland Cemetery T-MAX 100 is recommended for both indoors and outdoors at the ISO-100 box speed.

Alcatraz Federal Penitentiary This post isn't intended to be a 1:1 compare of the two films. All of the contrast comes from the film and modest postprocessing. None include the use of colored filters.

OCC B&W 2019 Hopefully, the differences of the two films are subtle, if at all, when looking at these scanned and processed images. The scanned JPEGs are all processed in Adobe Lightroom v6 and the posted JPEGs are resized to 1600-pixels wide to embed into this UHH post.

Old Ferris wheel All these images have some amount of film grain. Online sources suggest shooting the 100 at the box speed, but adjusting the 400 speed between 320 and as much as 1-stop at ISO-200. This ISO-200 idea is shown in examples below as examples 11 and 12.

St Patrick's Parade Kodak T-Max 400 is known for its fairly high contrast (in the highlights and shadows), its fine grain and its overall sharpness. Kodak literature claims its the sharpest black and white 400 speed film in the world.

Fort Gaines These next two images look at the same subject with the same lens, Chicago's Cloud Gate (aka The Bean), both in a winter snow, Feb 2015 and Jan 2021 respectively. Both use Kodak T-MAX 400, the first, example 10, at the ISO-400 box speed. Example 11 shows the ISO adjusted in the camera to ISO-200.

Snowy Cloud Gate This final image shows T-MAX 400 at ISO-200, with an additional +0.3EC for an effected ISO-160. We can see the details of the snow retained as well as lots of detail in the shadows. Although I'm really happy to pull of this action image in a snowstorm, I do feel some of the native sharpness of the T-MAX has been lost. In future rolls, I probably stay at ISO-400 with +0.3 or +0.7 Exposure Compensation.
