I preferred Pulaski to Crusher, actually. Crusher isn't a favourite character of mine, to be honest. I like the Picard/Crusher moments, such as they are, but on the whole, I preferred Pulaski. Dunno what she would have been like over the long term, though. Would she have mellowed or become sharper? How would that have effected the overall feel of TNG?
it would've felt like the LAST generation. she was antiquated (in universe) and a clone of mccoy, imho
fun for a season, perhaps, but tiresome in the long haul
