How much more tech is there really in a Gen 2 than a Gen 1, if you exclude the motor? Yeah, the EPAS is certainly a valid point, as are the Live Valve shocks in 19+ (but those can be replaced/disabled).
And note that when I say "tech", I mean overcomplex crap that breaks or can't be easily modified.
Sync 3 is certainly more advanced than Sync 1 or 2, but Sync 3 actually appears to be a somewhat robust design, whereas v1 and v2 are the miserable and spectacularly unreliable failure that is Windows Embedded Automotive. If I were buying Gen1 today I'd do a 13/14 and immediately do the Sync 3 retrofit.
Heated steering wheel isn't exactly rocket science.
Sunroof is a shit design in the Gen2, and was a shit design in the Gen1. It's just now a giant *************.
Both have big displays in the dash. Gen 2 is bigger in 802A but it's the exact same thing.
The early-autonomous-tech (adaptive cruise, useless lane keeping) might be an issue down the road, but think people have disabled that successfully. Doesn't seem to be a failure point from what I read here.
The 4G modem and FordPass crApp are easily disabled. I mechanically declined their privacy policy on day #1 with my gen2 (pulled 4G modem fuse).
I had my Gen1 for 9 years and absolutely loved it. Only had the Gen2 for 3 months...so far the same feeling. I did get the 7/100 warranty on the Gen2, but in retrospect I would've done the same for the Gen1.
All that said, don't think you'll go wrong either way.
