I vaped a Cleto, and I'm not a DL person so I can't really speak to the quality of the vape other than "too much for me," but I will say it's a well-made tank, the coils are pretty consistent and provide a decent sub-ohm vape and seem to last fairly well. That Cleto was my son's tank he gave me when he quit vaping, and he would typically run 250 ml of e-liquid through a coil before changing it (storebought, but not insane in gunking factors).
With that said, I hear nothing but good things about the Crown 3 and satisfied users. I'd probably purchase that over the Cleto (it does have some higher resistance coils for those who want that) although the tank setup and style would most likely not be as much to my liking (as my MTL tanks, not the Cleto).
I'd say both are decent choices, but if I were to recommend something, I would probably go with the Crown because I don't think I've heard a single complaint about it and a lot of rave reviews.
Best of luck,
Anna
