Tonal looks quite good in these comparison shots, although the photos are not identical in lighting and framing. The Plus-X looks overexposed and might have been better rated at 80 or 100. (Plus-X isn't as tolerant as some films.) In the overall scenes, the APX400 looks slightly better for my tastes, and the Tri-X looks comparable to maybe a bit better, but these are 400 speed films compared to a 100 speed film.
