The 2N2207 has a case style that became obsolete later, a metal cylinder with coplanar leads.
Holding the transistor so the leads point down and the ones that are close together on the left, it's E-B--C. Collector is distant from the others.
Some transistors in this case style brought out the case to a fourth lead. Those are E-B-case--C. They shielded C from B quite well, for neutralized common-emitter RF amplifiers.

TO-92: holding it with the flat facing you and leads down, most transistors with 2Nxxx JEDEC numbers are E-B-C, while most BCxxx Pro-Electron's are C-B-E. (And most Asian 2Sxxx are E-C-B. Never a dull moment!)

TO-92, and TO-98 ("plastic circular bottom with flat side on top section") parts always have coplanar leads. Perhaps you (Raymond) are thinking of TO-105 and TO-106, another early plastic package using an epoxy-capped ceramic header which put the leads in a circle a la TO-5 and TO-18, respectively.

TO-92 won the race because it's cheaper to make. Stamped lead frame, attach die, wire bond, jig it into the mold, inject, cut the lead joins and you're done.

And that is it.

Text mode makes layout a bit confusing, on my screen at least, especially for the plastics. One might add the layouts are all bottom view. Some TO-92's have a triangular lead configuration like the metal cans TO-5, TO-39, TO-72.
Bottom/top view distinction is clear for the cases with emitter tabs and irrelevant for the linear arrangements.
By far the most common cases were TO-5, TO-39, TO-72 and TO-92. The flat side of the latter corresponds with the "empty" area on the metal cans' pin layout, leading to the same CBE-arrangement, which is why I considered that the "standard" arrangement.
