Is there a little offset in the alignment?

No. For simplicity they are center-to-center. The offset - about 0.005" each side - seems to take care of itself in the flex. Test cars ran through it fine, just wheel clicks on the small gap.

I'm not crazy about the rail gaps, and what is the joiner going to look like after painting?  I fear it may seem a little clunky.  I'm still a fan of crushing half a rail joiner and soldering the joint together, but I can very much appreciate the need for this joiner to speed up track laying.

Yeah, I've done the crushed joiner thing in seven or eight spots and, frankly, every one was a fraught process. With my yard and industrial plan, in the end I think there are going to be close to 100 transitions, so something in that process had to change. Not nearly as clunky as Atlas insulated joiners, which I have been using in certain instances such as crossovers, albeit foreshortened to reduce the mass. I may mod this transition joiner for C55-C55 for that very reason.

The gap is not as bad as you think, hard to see but there is a filler tab.

Yes, sir, I couldn't see the filler tab in the photo.  That addresses my issue with the rail gap.
