I don't know, to each is own but this has been the best Smash Brothers installation to date for me. I've "only" logged 80 hours so maybe I haven't had a chance to get bored yet, but I got pretty much what I wanted in a mobile Smash Bros.
Online is viable and only about 20-25% too laggy to the point of irritation for me
I can play with friends at a restaurant, which has never been possible in Smash before.
I can focus on unlocking custom moves to then use on the Wii U's more extensive content/Amiibos (again, $20 more)
The matches I have had on this handheld have greatly surpassed all my non-modded Brawl matches in terms of fun and competitiveness.
I get the Wii U version will be more desirable, Smash works better overall on a console as it stands with current (Nintendo) technology. But to even consider that they should have just ignored a 3DS Smash is...Surprising? Like what I am not getting is what magic is the Wii U version going to throw at you that will make it IMMENSELY more superior than the 3DS version that we didn't already know?
We knew the Wii U version would be a more fulfilling experience because of the new tech, larger screen and controls. We knew that there would be more content because it was held back later and they can cram more data in to the console version. So then....What did you expect from the 3DS version?
It would be misleading and unfair to toss it out as a watered down Smash Wii U. That's not fair to the concept of a mobile smash brothers. Some balls were dropped (Smash Run, the exclusive feature of the 3DS, not being online really is counterintuitive), I just hope people at least appreciate what we were given here. And outside of the lack of friend-adding, I do not see a problem with the online.
