It is my own experience that implementation is at least as important as tweeter type. I have used Ionic, ribbon, and many different types of domes. The first two have many virtues but are hard to match with standard cone speakers. I have tried titanium domes and find I prefer soft domes to them; this is a personal choice, not "better" or "worse". As I like Scanspeak I decided to try some speakers with the "Revelator" tweeters, I have purchased some but not yet received them.
