I own a 2015 leaf, and drove a 2021 S Plus for a week. It’s basically like the first gen leaf but with more range (and a few fancy driver assistance features like adaptive cruse control). Oh yah, and rear USB power outlets….

Three minor things I felt that the 2015 leaf did better than the gen2 2021 leaf:

Driver sunshade did not have the “pull out” tab to extend the shade (and could have used it)

Not a fan of the new center console. Arm rest wasn’t as big, drinks are in a more annoying spot. I mean, it’s FINE….but I liked the 2015 model year better.

Gen 2 has an analog (dial) speedometer in the main cluster. I prefer the heads up digital speed gauge in the 2015. But to compensate, the cruse control tells you what speed it is set to digitally, and that’s basically what I use for all speed control anyways.

So, no major complaints about the 2nd gen plus model, I did really appreciate the adaptive cruse control (e-pedal was fine…not worth upgrading for…) loved the extra range. Dash has a lot more informational options (more than you really need, but whatever…)
