Regarding acceleration, I gleefully like to show these monster vehicles around me just how sprightly the i-MiEV is. That said, stomping down on the Tesla's accelerator is second-to-none when it comes to exhilaration.
Agree with you regarding regeneration, as I've been a strong proponent of heavy regen for years, as well as fingertip control over regen (such as a paddle or the joystick I had on my modified Gen1 Insight). I also want to temper heavy regen with the ability to have zero regen and not have to kick the car into Neutral to do that. I haven't driven an i3 lately (the first ones had superb regen which was subsequently reduced by BMW), but the Chevy Bolt has one-pedal driving with a simple paddle and the Kona EV / Kia Niro EV have two paddles (one increases regen the other decreases it) and which actually provide a zero-regen setting. Hey, the world is evolving and manufacturers are finally responding as customers like to be able to adjust the car's regen settings (as well as creep) for themselves. Don't forget, the i-MiEV's design is over ten years old but yet provides three different regen settings (4 if you include Neutral).
Lots of new electric cars are on their way, so they'll hopefully only get better and more EV-feature laden. The experimental electric Mini of ten years ago (only leased) was absolutely loved by those who drove them, and did not want to give them back!
Around here, a used 2011 Nissan Leaf (and its questionable battery) can be had for US$4500, I helped a fellow buy a nice 2012 i-MiEV with CHAdeMO for US$4000 earlier this year. The peppy little Fiat 500e (which has never had a DCFC option) goes for about $6500, the really peppy small Chevy Spark can be had for $US5500, BMW i3 are still over US$10K, and then there are the newer cars just coming onto the used car market such as the Chevy Bolt now in the low US$20Ks, with older Teslas being the bargain of the century IMO. As with all used cars, it all depends...
Have fun exploring.
