Looks like it's a good argument if african mahogany and sapele are the same.
Or was. I guess not.

Smoke developed classification: N/A
Stifness: 1704 per 1000/psi
Bending strength : 17895 psi(Dry)
Stability:Very stable and not subject to dimensional changes once dried.
Workability: Good to work with in general, except for interlocked grains which is difficult to saw and plane.
The sapeles I've come across are dull when bounced. So I've never bought one.
