The finishing on the MIJ is simply spectacular. All flat painted surfaces are window-glass smooth, EVERYWHERE. This Aerodyne Special has a painted headstock, and the buffing and cleaning even way down into the truss rod access recess is simply sublime. Usually this is an area where they say "eh. Not worth it." and you often end up with lumpy paint and/or excess buffing compound caking up the area. Not so with this thing! It is surgically clean in there!
Hardware is better than most, as well. REALLY nice Babic bridge (probably a $150ish bridge, retail), sweet tuners that feel better than the standard jobs on my MIMs, and on par with the current MIA tuners. This bass has standard single-coils, but with them both on the bass is DEAD silent. Zero self-noise. I can even roll back the bridge pickup to about 75% and it still remains noiseless but gets to that perfect warm bark that is just to die for! Nice and fancy solid metal/chrome control knobs, too.
We now live in a world of $900-$1,500 Made in Mexico basses. The quality of MIMs, to me, has not changed much from the first MIM Jazz Standard I bought in 2001. I don't know what the MIJs were like 20 years ago, but after 25+ MIMs and 4 MIAs in the last 2 decades, I am truly impressed by the recent MIJs I have played. I do not have experience with CIJs/MIJs of yesteryear.
When MIJs are trading within the same price range as MIMs it becomes a no-brainer to me, if there are MIJ models you are interested in. Yes, these specific International colors are a bit out there, and I also am not a 3 bolt fan. However, they're replicating a very specific range that has its own fan-base, and I hope they do well!
