I love HootSuite.  It was the first multiple Twitter account “management” system that I used.  I switched when TweetDeck gave me better options.  Later TweetDeck updated and although it still has many features that I find helpful, it does not match the speed or provide the layered functions that the current HootSuite provides.  There was only one feature that TweetDeck provides that I was missing.  It didn’t take me long to discover that HootSuite actually had a better feature that gave me more focused information than what I thought I was missing. With HootSuite a quick click will provide you with the previous tweet that your tweeter was replying to.
