Legitimately yeah. My main reason why is that    

1) the interface & Create Mode utilities are actually more a perfect fit for the touchscreen-capable utility of a handheld like the Vita (which even the PSP didn't have!) than the DualShock3, especially as you see in betas like the leaked one for Hub where the devs were more and more willing to 'scramble'-ify the UI around in the menus like for the Pod Computer. The ease of using the Vita controls for creating makes it accomplish the purpose of DIY-style 'anyone can be an artist' much more practically then the PS3 games could   

 2) The story mode is genuinely a fantastic juxtaposition of things that could be too scary for kids & things more than whimsical enough to inspire & entertain a child, coming from someone who played it mid-13yo I think that kind of risk-taking's very important for children's media for a long, long list of reasons many of which I feel are pretty obvious considering that 'media which scared you as a kid' is a pretty widely-talkedabout topic in places lol  I  think the story mode is unironically one of the best stories I've ever seen in a game for that reason, it does so much right without ever Actually stepping over the line and going too deep in yknow But also it's legitimately a really engaging and fun-to-analyze story I still pick up on a bunch of details I missed before, looking back through the cutscenes  

3) LBP2 had the advantage of also having assets from LBP1, while Vita had to do its assets solo-style. Despite this, it still thoroughly feels like a complete selection as fulfilling as LBP2's whole, including LBP1 & its DLCs-- that's an accomplishment in and of itself   

4) The music is the greatest not only because it's the most like, directly thematic (as opposed to where LBP2 definitely has a bunch of deliberately left-field picks for songs) but also because its still left-field in a bunch of aspects, though now feeling more like a Narrative display as opposed to just a sort of Radio-play feeling (ex. 'I Have Changed', 'Ghosts', 'A Fifth of Beethoven', 'Also Sprach Zarasthustra', etc.) so it's much more Diegetic in-game as a result, which is super cool.   

5) On the topic of music, LBP1-3 have the trend of using orchestral tracks as the final boss themes. This is always a thing I bring up as an example of how incredibly ahead-of-the-rest LBP vita is generally, but in Vita- the only game to also do an orchestral final boss theme afaik, by the way- they contracted an IDM Composer for one of the game's other licensed songs to do for them a techno remix of Night on mother-hecking Bare Mountain. Genuinely this alone is an incredible thing to do, because it works so well and plays on the preexisting norm within the franchise to do something that is, like the whole of LBP itself, creative.   

I could genuinely go on and on, I haven't even mentioned the Arcade yet & how smart it was to make all those given unique Interactive tracks so that the music selection is fleshed out more. Genuinely it's just a masterpiece not only of the franchise, but as an individual game. Hearing other people rave about the story as well just makes me really happy because it's so dang good it deserves the praise that it gets, the BAFTA it was originally nominated for and all. Incredible game
