CLEAR plus TSA Pre-Check is an unbeatbable combination. I fly out of DEN once a week. If the TSA Pre-Check comes through, my total time going through security aveages about 3 minutes. Without Pre-Check you will be subject, of course, to the standard security search, but CLEAR cuts out the whole first step of waiting in line to have your license/passport checked. How often do we show up two or two-and-a-half hours early because the biggest crapshoot of the day is the length of the security line. For me, at least CLEAR provides some assurance that I've already won half the battle of getting through security. If the Pre-Check comes through, it's a complete victory.
