pro's:
both are good for lean mass, cutting, and strenght gains
lean mass gained from oxandrin is very likely to be maintained
oxandrin is a pretty low side effect drug in comparison to other steroids
1-test has been very effective for many
no conversion (or very little) of either drug to estrogen
con's:
no conversion to estrogen (i say it's a con because lack of estrogen tends to make people tired and can screw up lipid profiles - lowers HDL)
1-test is rough on the hairline for some
1-test shuts you down hard, and oxandrin is also suppressive, so post cycle therapy is necessary
BTG is very expensive
oxandrin is 17 alpha alkylated, so it is potentially liver toxic, although there is conflicting views as to how toxic it really is - liver protectants such as R-ALA and milk thistle should be used
that's about all i could think of right now....i'll add more if anything else comes to mind
