It's not called Walt Disney Land it's called Disneyland Resort so it's DLR
and besides, neither one is necessarily "better", both have different strengths and weaknesses. for example, the POTC in Disneyland is by far the better version, it's much bigger and includes so much more detail in its scenes while the one in WDW is considerably smaller and its details are in its queue not ride. Meanwhile, the BTM ride in DLR is much smaller and doesn't bring out its full potential like WDW does, in both ride and queue. Size doesn't necessarily equate to quality in this sense, each park has things the other one doesn't have and therefore something new can be given to you in each experience.
Personally, I do like WDW more but this has more to do with me growing up with WDW more, as well as yes its size does give its aesthetics more space to look nice in and to also allow guests to have much more options during their stay. But it doesn't mean I think it's better than DLR, because some things in Disneyland I do honestly think are better than their WDW counterparts.
