Infinite aerial pkt1
Pkt1 has more hitstun (I think this was in, I didn't really notice it that much though...)

JC'able psi magnet. Comes out in 3 frames. Has a lot of aerial lag.
Pkt2's damage was increased.
Please note that I pulled off the data from the 7/10 changelist off the top of my head since I can't find an official one. Here's a link to the current changelist:

By gimmicky moves, I mean the new Magnet and to an extent, Dsmash. 7/10 Ness's specials were never as gimicky as the new Magnet is. You can argue that the infinite PK Thunders are gimmicky, but those just improved the PK Thunder's uses which he already had. PSI Magnet, however, changed its entire purpose, and while I personally don't have much of a problem with it, I'd really rather keep the great edgegaurding tools he was given in 7/10 than nerf them in exchange for a gimmick like Magnet, but I do like your idea for a new magnet even better.
Okay let's compare the specials with the list I have above.
Pk flash: In 7/10 it's speed was increased. Didn't really matter though since the projectile itself is so slooow. I'm able to use it for edgeguarding like I did in melee. Learn which recoveries it can be used on (ie, don't try it vs. someone like Kirby). 7/10 is obv. better but the difference is barely noticeable IMO...
Pk fire: 7/21 holds people in better. With the higher sh in 7/10 he might have been able to do double aerial pk fire. In both builds pk fire was sped up and he can do FH "lagless" aerial pk fire. 7/21 is better.
Psi Magnet: Lots of differences here. In 7/10 he could jc it and it came out in 3 frames. Had a massive amount of aerial lag and couldn't be used to semi-stall in the air. This focuses on the healing aspect of psi magnet. In 7/21 it was sped up to come out in 7 frames, given sa on the startup, and the wind effect was buffed. Try using the
grounded wind effect to punish recoveries that overshoot the ledge. I have sometimes managed to combo into dair with it and edgeguard spacies up-b's extremely effectively. A lot still needs to be tested about the move. I think 7/21 version is better since it helps in more matchups and can really **** some recoveries.
Pk Thunder 1:
Grounded pkt1's are virtually the same. Pkt1 7/10 had more hitstun but the difference was barely noticeable. The startup lag was buffed in 7/10. The 7/10 build also had infinite aerial pkt1.
Pk Thunder 2:
It did more damage.
Final Edit: Please don't call a d-throw that combos and a b-throw that kills gimmicky.
