"Are hybrids any easier to grow or heartier than regular or cloned orchids?"
In some cases yes, and in others, no. Typically, a hybrid will be more tolerant of less than ideal conditions than a species orchid will. This is due to what is called "intermediacy." For example (an extremely simplified example), if you took an orchid that's natural habitat is a cool alpine cloud forest, and crossed it with a sea level warm growing orchid, you would get one that likes a temperature range somewhat between the two.
As far as phals are concerned, they're all (especially hybrids) pretty tolerant and adaptable. They've been bred for years and years, and one of the reasons they're so often recommended as beginner orchids is because they are so tolerant.
As far as heterosis, or hybrid vigor is concerned, there's also a flipside. The opposite of that is genetic depression. The progeny can get a better combination of genes than either of the parents, which results in a more vigorous growing plant, or it could end up with a worse set of genes, making it unfit for survival.
Phalaenopsis Fancy Musick is a hybrid formed when you cross P. Micro Nova with P. equestris. P. Micro Nova = P. maculata x P. lobii.
