Lesser?
Invariably when I see sentiments like that it is made by someone who has never been to DLR and is just passing along "what they have heard", or has not been in many, many years.

So I hope you do not put too much stock in them.
It is true that in some ways DLR is lesser than WDW, but it is also true that in other ways WDW is lesser than DLR. On the whole both DLR and WDW are full of Disney magic.
DL itself is now a park at the Disneyland Resort (DLR) which also includes Disney's California Adventure (DCA), Downtown Disney (DTD) and three Disney hotels.
DLR does not offer as much to do as WDW and it is therefore true that a DLR trip is usually
shorter than a WDW trip. But that does not in any way mean it is
lesser.
Here are ways I think DLR is better than WDW:
1. Higher ride concentration - WDW's four parks have only 10% more rides than DLR's two parks.
2. Proximity - everything is closer together which means you can walk everywhere and not waste time on transportation. It also means it is easier to take hotel breaks, park hop, get to dining at DTD, etc., and at bottom it is easier to experience more in a given amount of time.
3. Weather - less rain, less humidity, more sunshine.
4. Better shows - Fantasmic is better at DL, Aladdin show is better than any of the WDW stage shows, and when Remember Dreams Come True is showing it is the best Disney fireworks show ever.
