I don't think Clear is worth the cost, especially when compared to Pre or in addition to Pre. If you had other uses or were flying at least monthly it might be. Of the 10 times I've flown over the last two years, having Clear would have saved me maybe 10 minutes total. Really the only way it saves time is that it gets you past the ID checker, which usually isn't where I'm stuck waiting. If you got a free trial and don't have Pre, it might be worth it, but you have to go a facility to set up your account and verify information before you use it the first time.
