The Roland card sounds good, but only when run through an amp or some kind of amp sim. The Rhodes are nice, but they are a little too nice. Great jazz rhodes, but not really spanky dirty ones. But if you overdrive it and like editing patches, it sounds extremely realistic. I haven't tried any of the others you mentioned. If you don't want to spend time tweaking, and don't want to run it through some effects processors or a decent amp, it's probably not going to suit you just going right out of the synthe to the main mixer.
