yeah, there are lots of differences and lots of variables, for a better understanding, you might try searching the archives at the TDPRI site in brief, the 3-saddle vintage bridge will not intonate properly with a standard-gauge string set--the compensated saddles address this issue (i'm not sure if that photo you posted is truly compensated--it appears that the angles aren't correct, but anyway) the 3-saddle bridge can have various metal barrels, which will increase or decrease the 'twang'...but in general, the traditional tele twang is from the 3-saddle bridge...there are varying positions on the 6-saddle vintage type, and i haven't played one enough to have an informed opinion good luck:)
