Feature-wise, they seem "close enough", as you detailed. There's not really one deal-killer.
If anything, I have more confidence in Ford making rapid improvements in the software/connectivity/IT area.
(Nissan has already shown themselves slow and confused in the Web-side portion, or at least poor in their choice of subcontractors.)
I've said before that the L3 isn't useful to me (with the paucity of L3 chargers likely to continue over three years), and 6.6kW is very useful.
But really, it's back to styling and appeal. I've never been a fan of the Leaf styling or interior. I'd rather have that Ford.
On the other hand, I'd rather get into a Nissan than a Ford, just based on track record and previous cars.
I'm buying (ok, leasing) a Leaf because it's FIRST.
The longer Nissan leaves me in frustrated Pending limbo, the less I feel like doing business with them and waiting to find out if they are First. If Ford can put one in my driveway first, with superior styling, I'm there. I'd pay an extra $5k, since that's the CA rebate I'd likely miss by being Pending.
