Guitar playing audiophiles, Martin or Taylor?

My "other half" is exploring the stress releiving effects of playing acoustic guitar. She's a great woman! She actually convinced me to buy a pair of Rowland model 9 monos w bps, instead of a boat. Thats my girl! Anyway, shes been playing for 1.5 yrs. Its a toss up between Martin ???? Koa wood, Taylor 314ce, Takamini GS330s, and a Tocoma???sound hole on top!!! All these models can be had "used" for around 900.00 All replys welcome, thanks Scot
