I've only had exposure to the series' which had domestic releases, namely the original, Ultra Seven, Ultraman Tiga and a couple of the movies. Of those three series, it depends what you're into. If you want Showa style, then the original and Seven; Heisei style, go Tiga. You really can't go wrong with the original, but there's a distinct show formula for every episode. Seven changes that up nicely. Tiga does too to an extent. Tiga and Seven have some heavy similarities with their respective EDF's.
I saw the original first, Tiga second, and Seven third. I'd recommend starting out with the original. You don't have to watch *every* episode though. You could probably quickly research the major/memorable big bads and just watch those episodes. Although at least watch the final episode before moving on. Seven's origin is a bit confusing, so that's probably not a good place to start.
