Is it? I've never been, but other than the People Mover, Astro Oribiter, and Carousel of Progress, what makes it better? Their Space is outdated, Tron isn't very good, Stitch is empty, MILF is outdated, the Speedway isn't much. Star Tours, Space Mountain, Autopia, the Monorail, and the lagoon make for a much better Tomorrowland in my eyes.
First of all, Space Mountain in WDW is no more dated than Matterhorn is, and it's the only one like it in existence, whereas the DL one has been copied elsewhere (granted the Tokyo one is gone now, but it also exists in Hong Kong).
Star Tours exists in DHS, and has a much nicer facade (it's an AT-AT Walker that periodically shoots, very cool. Then you go through the forest scene from Endor if the line is out the door; during the day, it plays Star Wars music, and at night, you hear Ewoks). Not to mention with the blessing of size, it's got two additional speeders and I believe there's an additional row in each speeder, so it generally has pretty short waits. I don't wait if I see it's posted more than 20 minutes.
I'm not the biggest fan of the submarines (I'm sorry!) They take forever to load, and for me, they make me feel claustrophobic. Packed like sardines in a can.
The monorail at DL is very much an attraction. At WDW, it's very much a mode of transportation. It's still fun to ride, but we're using it to get someplace. Bonus: if you don't have park tickets, you can ride the monorail or the Skyliner.
But now, back to the original discussion: Aesthetically, MK's Tomorrowland is much better. In spite of the former Stitch area not being actively used, there's very little dead space. Unless you know that SGE was there, you wouldn't know anything is supposed to be there. They use it mostly for stroller parking, and I've also seen them use it for meet and greets and as a thunderstorm shelter. There's very little they can do with that space because it's small and backs up to the kitchen at Cosmic Ray's. On the same note, they can't do a lot with the Laugh Floor space because it backs up to the Tomorrowland Terrace space.
Speaking of Cosmic Ray's, we can't skip talking about Sonny Eclipse. He's been a mainstay of the place for years. They need to improve the food, but Sonny Eclipse makes that place.
Back to little dead space, Astro Orbitor is at the center (where it belongs). Underneath it is the Peoplemover entrance. Underneath that is the Lunching Pad, which includes additional seating.
Over near Tron is an additional place selling frozen drinks. There's also a churro/popcorn stand, as well as my favorite, Joffrey's. The fact that Joffrey's barely exists at DL is a topic for another time.
MK's Tomorrowland has also been better maintained. DL's Tomorrowland is the only place in the park that looks worn. MK's got a refresh along with the addition of Tron.
The only thing I'll say is that Buzz really, really needs a refurb. They also could probably take out the speedway and do something else with that space. They are limited in how far they can expand out because, well, swamp.
