How does MX103-104 compare to A314?

Both MX103 and MX104 state “This mix is a variation of the classic trust and respect pheromone formula AlphaA314.” So how does it compare? A314 is pretty much out of my price range for a while (wife’s b-day is coming up, planning something special), but these are in the affordable range. Is it primarily a scent mix or is it a new formulation? I realize there’s a difference in spray vs. oil, is that the primary difference?

If you don’t think it’s that great, did you try the original A314 with good results?

If you do like it/them, have you also tried the A314?
