Disney world's may not be as spiffy as some of the flashy things on DLR's, but if you look at ride experience overall, WDW takes the cake. It's faster, unpredictable, taller drops and better sound effects. I like having speakers long the track more than on the train because it has the effect of things flying by, dimensional sounds.
I can't emphasize enough how dull DLR's track is. It's a spiral down, with no drops or surprising twists.
Oh and yes, the small trains rock.
DLR's version is one right turn after another...pretty predictable. Also, the drops virtually don't exist.
If you want proof of the intensity levels, Disney World's has a higher high requirement.
Oh, the sheer scale of WDW's is way impressive. The size of the building, the queue and load platform are all bigger and cooler. DLR's looks dinky, especially since the queue is outside in front like it is.
I'm not sure, other than maybe some different effects, what could make anyone consider DLR's lamer version superior.
Did I mention how dull the track was at DLR?
The west coast version of space mountain is so much better it's not even funny. First off, you sit side by side, so you can hold onto and talk to the person you're riding with. (My wife, who won't usually ride coasters rode this and would ride it again.) Second, it was silky smooth compared to the florida one. Space mountain in Disney World reminds me of the matterhorn at disneyland. You sit in the ride vehicles the same way and the ride is equally rough on the two of them. Also, the one in California has the halloween theming of Ghost Galaxy, which is a visual treat during the ride instead of just seeing the glow in the dark strips on the other cars, which is pretty much all you have to look at in Space Mountain Florida.
(I like this topic, by the way. I tried to hit all the parks I could in california and made sure to go on rides that were on both coasts to see the differences.)
The newer Disneyland version was a vast improvement in ride quality and the onboard sound system greatly improved reliability of the sound. I heard MK's sound system on the track didn't help things and many guests will barely hear the sound track. I guess I will have to try it again at MK.
Oh, Ghost Galaxy at Disneyland is a terrific improvement. You gotta try it during the Halloween season.
By a score of 3-2, I give it to DL.
