The A442F is much more reliable than the A343F.
I question the accuracy of this statement. Any proof for it?
In comparable condition I'd pick the later model every time, personally.
ODB2 is probably the biggest difference that I care about though parts availability and the easier to manage headliner are relevant as well. The ODB2 benefits for me are that I can easily scan/monitor codes and other outputs from my phone (via bluetooth connector). It also means that the FI system is easier to maintain overall as there is no NLA/hard to find AFM, hard to source o2 sensors, etc. like the earlier 1FZs have. If you've been involved with long term FI system troubleshooting on an earlier 1FZ (which I have) the value of ODB2 and the later system only increases.
If one or the other is in better condition to a relevant extent (maintenance, rust, cosmetics, miles, etc.) then I'd pick it every time, regardless of the year/setup.
The main benefit of the earlier models that I see are the manual/cloth seats but that's personal preference and one could argue for either seat being superior.
