Act 3 is much worse. There aren't very many vendors on the nameless isle, they don't sell much variety and there are a lot of gaps in what they cover, plus most of them end up going hostile at some point. Arx is better with many more vendors, but all the vendors there are still very low stock so it can be really hard to find anything good for certain slots
I wish it were more like act 2. Mostly I just think there should be a vendor like the Raucus One in every act/area, maybe on the ship?
