@fn0rd from a player perspective it is not more rule-heavy than dnd5e - but you have more options. Which is nice, but can also be a bit overwhelming. The rules are very well balanced, you can play about everything without having to worry about not contributing.
From a DM perspective there are more rules, but they actually save you time and effort. A lot. As a dnd5 DM you have to balance every encounter yourself, the CR system is broken, and let's not begin with stealth...
