It sure is. For comparison check this out. By any standard this image
(credit: T. Boroson using the 0.9m telescope at Kitt Peak) is a fabulous view of the Sombrero. But just look at the difference in detail in the dust lanes of the HST image, and ESPECIALLY the disk of the galaxy. I've seen dozens of photos of this over the years (the Messier objects are very popular because they're relatively bright and therefore easy to find), but none that even came close to this detail. Truly a first-class example of what the Hubble can do.
(Although I have to say I'm not sure about the "most photogenic". It's hard to beat the Andromeda Galaxy.)
