I've graduated (some above would say descended) to Reos.
They are not sexy. They just give me the best vape, period. Essentially, they're a dripper with the juice being fed by squeezing an onboard bottle - the 'clarity' of an RDA with the convenience of a tank. If all that talk is hooey to anyone, so be it (different strokes and all that).
Clearos are great and the art form is definitely advancing with tanks like the Nautilus. They'll be around for as long as vaping remains a thing, and just as with cars, some folks will want reliability, convenience, ease, and cost effectiveness, while others are passionate about tinkering and tuning.
I think the market is growing at both ends and we're all better off for it.
