If they both tell time, then I'll say that the Casio is better.
I own a Casio and way more expensive Citizen watch. Guess which one never gets worn to work and is little more than a piece of bling?
Unlike the Casio, which gets banged up and needs replacing with another $20 watch every couple of years, the Citizen will likely last forever, based on how it's treated. It would also be great to say that I purchased the Citizen watch because I like bling. I didn't; it was a gift that I wouldn't ever purchase myself, but don't mind wearing on occasion. I'm not a man to wear jewelry; however, I wear a watch 24/7. When I dress up for events my wife deems important I'll also wear the watch she bought me way back when.
In comparison, your engine will also likely last the life of the vehicle, regardless of whether you use high-end OTS oils or pay 50-100% more for something boutique. Heck, your engine will likely last the life of the vehicle, even if you use the cheapest correctly-spec'd oil you can find or get on-sale, as many here seem to do.
