I don’t suppose either opened the door first . . .
When it was just the Miata in my two car garage (my wife’s van won’t fit under the door), I backed in–in something that size, you want every last scrap of visibility.
When we first added the '72 Caddy convertible, I would back it in, with the Miata going in head first, so they could open doors into the same space (I’d built a 2 foot deep shelf setup on the entire side of the wall).
That gave us trouble getting around the caddy and opening the freezer door, so I switched the two the next time the 72 was under power (they don’t run so well with the carburetor on the workbench . . .).
And when the Miata died yet again, the '97 Eldorado Touring Coupe took its place–but after a while (and catching the mirror on a box someone left hanging out of the shelves when I backed in), I usually drive it straight in, keeping the passenger window a couple of inches off the '72 as a guide.
I’m not sure what happens next–the '97 is going to classic status but wants to keep the garage for it’s factory perfect paint (it just had a minor collision that resulted in a total loss payoff and salvage title, so I can’t get normal insurance again), so I’ll probably find myself parking in the driveway–but with the van on one side, and the mesquite tree on the other that’s big enough to shade the van, it will not get much direct sun . . .
