I would go for 2 personally... Coin 3 the offcentre thing rules it out for me.
Coin 1 is not unattractive but the details do not jump out... perhaps weakly struck or a little worn. It's plus is that it is a tet, and I love a large silver lump.
Coin 2 is not so large as 1, but a drachm is still a decent size to see ^^ the portrait is the selling point, it really stands out, the toning is not unattractive, the reverse is cool and it is both sides are well centred. Also it has a little provenance and is a good price for its type. So that would be my choice.
