Properly rebuilt by someone knowledgeable, the Twin Ultramatic should be just fine and not really limiting the driving experience in any way, but then again I'm a purist. Some folks have done the conversion to the Chrysler Torqueflite 727 trans and are happy with it, no doubt you'll hear more from them. This conversion kit is widely advertised in PAC publications and other hobby publications. And I've heard other chit-chat about adopting more modern GM transmissions with an OD feature.
