Asus or Creative sound card?

I want to replace my creative x-fi platinum sound card. I use a crappy Behringer uca222 with rca inputs to record audio. There is a lot of background noise, hissing, etc.



So my preferences are the Creative ZxR and the Asus Xonar Essence STX.



I use a Tascam 8-track digital DP-01FX to record. So I often record audio coming from my Tascam to my PC (using wavelab) and rca ins/outs.



I want a lot of compatibility. the Tascam has Midi, rca and digital (SPDIF I'm assuming?) outputs. (so SPDIF is better than rca?)



I have a usb midi cable which I'm assuming works fine.



Any preferences or insights or suggestions?
