I've used sonosite and philips extensively. We had an x-porte and edge in residency and it's the initial machine I learned TTE on. In fellowship they had an exclusive contract with philips (Sparq, IE-33, Epic7c, or CVx). I've also used some of the GE ultrasounds in the pain clinic.
My answer would depend on who's paying for it:
If i'm paying for it out of my own pocket, I'd go with a Sonosite Edge (yes the edge and not the xporte, i'm not paying $70k+ out of my own pocket to get an xporte) with the two probes (i think anything up to 12 Mhz for linear is fine and any phased array probe is usually enough for POC ICU needs), should run me about $25-30 for the probes including ability to save and print images.
If the hospital system has a contract with philips, I would get myself an Epic 7c with a L15-7 and a X5-1 probe. i think this would run about $300+.
*My answer also demonstrates why health care cost is high.
P.S. I don't know why you are comparing the xporte with the venue, the Sonosite SII is more of a in class comparison to the ge Venue. The xporte is more meant to be overbuilt into like the sparq or epic class.
