I find it depends, and that's highly subjective for everyone. 4E is uniform for everything. Some like that, some don't. 3E has basic combat, vancian magic, a maneuver system, incarnum system, psionic point system, invocation system, etc. Some like that, some don't. However, the one uniform thing about 3E is rolling high is always the goal. You're always adding and always looking for the higher number when resolving randomness for tasks. In 2E, you wanted to roll high for saving throws, low for proficiencies, and do algebra for THAC0. For psionics, you wanted to roll low but not a 1, some number between 1 and 20 was your sweet spot perfection calculated based on the individual science or devotion, and 20 was bad!

Subsystems aren't inherently good or bad. It depends on the implementation.
