What are the things you miss the most about Kevin Moore and Derek Sherinian?

I mean, I love and respect Rudess for everything he does in Dream Theater, for his huge impact in the songs and his musicality, but I can't help but think how different his playing is from Moore and Sherinian (which is perfectly normal). For example, I love the presets/sounds Sherinian chose to use in some live versions of Awake and for A Change of Seasons or how Moore perfectly suits in Images and Words. What about you? What are your thoughts?
