The best thing you can do, especially as an experienced rider, is try to demo as many kites as you can, North and other brands. It sounds to me as though from what you're saying, any of the three North kites you've chosen will probably make you happy.
Unfortunately you'll find there is no such thing as the 'perfect' kite. Our best jumping kite is definitely the Rebel, it is very fast through the window, which gives it the great jumping and also gives it great upwind ability. I don't have a ton of experience looping the new Rebel, but it seemed better to me than previous years for looping, a more steady pull rather than slippery/whippy feeling. It also needs a little more experience with sheeting, you'll want to be good with your timing on the sheeting to make sure it climbs back overhead quickly. The quickness with which the Rebel gets to the edge of the window can be a detriment in the waves, but the 2018 Rebel is very stall-resistant, so, especially with a twintip which tends to not go as fast down the line with a drifting kite as a surfboard I don't think it would be a huge problem for the riding you're describing.
I have no experience on the 2018 Evo, but I know that in previous years it was a really good jumper as well, almost as good as the Rebel, with the added benefit of being a bit more forgiving if you didn't get your timing/redirect/sheeting perfect. The Evo has looped more quickly than the Rebel in the past. It gets through the loop and back overhead quicker, which can be good, but I also felt that it didn't give you as powerful/satisfying a yank as some other kites. As an all-around focused kite this should do you better in the waves than the Rebel, though I wouldn't define it as a 'wave-oriented' kite.
The Dice is a really solid option as well, especially if you have any interest in trying to unhook in the future. I'd just about guarantee it will outjump your older Bandit (delta-C kites were not known for their top-end or big jumping ability) but it will probably not get you up quite as high or hold you up quite as well as a Rebel or Evo. On the plus side, the looping of the Dice is really really good. Very consistent, very powerful, quick to get around and climb back up but with a satisfying pull all the way through. Of the three this is also the best wave-kite, being a well balanced 3 strut kite it can drift well when you turn down a wave with the wind, however as I mentioned above, this generally doesn't apply as much to twintips which require a bit of power at all times, lacking the volume/speed of a directional.
In short: biggest jumping, best for old-school, go Rebel. More forgiving/easier riding, still great for old-school, slightly better in waves, go Evo. Decent old-school but more emphasis on progressive riding/waves/kiteloops, go Dice.
Again, I think any of these kites will be a significant improvement in terms of jumping and range compared to a 2012 Bandit (this is not a slight against Bandits... I'd say the same thing if I were comparing to a 2012 Evo, which would be our closest comparable design), and I'm guessing any of them will make you happy. I'd highly recommend demoing them all (and adding anything else you can find to demo). If you can't get out on these kites, hopefully this helped. If you do get a chance to test these, feel free to let us know your thoughts, and if anyone else has anything to add that I've missed or fully gotten wrong, also feel free to jump in.
