When it comes to the Southern Leaguers, Old Mill SL backs typically do command a slightly higher premium over Piedmont 350 SLs. I think many collectors like the OM SL backs as they indicate 'Southern League' whereas the Piedmont 350s do not. Also, Piedmont backs are more common than Old Mill backs in general, although Old Mill, Southern League or not, isn't considered a scarce or rare back.

Of the 48 southern leaguers in the T206 set, 34 can be found with Hindu backs. These definitely command a premium over the OL SL and Piedmont versions due to their scarcity. In recent years, Hindu SLs have commanded very high premiums over OM SL and Piedmont.

Then, for those who consider Coupons to be part of the T206 set (I do not), the Coupon SLs can command prices even higher than Hindu SLs.
