I think zoos are for the most part much easier to keep than sps, sps can be very finicky with lighting and flow.
However, my experince is it can be much harder to keep zoos and sps in the same tank, mainly because they do have different requirements, most zoos from my experince can do very well with lower lighting and too much light can fry them, and can tolerate a "dirtier tank"
Zoos can be difficult to get them to grow quickly though.
As far as names, having left the hobby and come back it does suck now that people are selling them so high, even fellow hobbyist. There main benefit that I do understand with the names is some corals can really become a currency that you know what you will be able to get for them money wise, trade wise. But now that eveyone is naming there own its getting ridiculous espeically since there are so many similar morphs.
I do think you see more an more hobbyist almost becoming mini retailers and giving tiny frags to fellow reefers. I really wonder if they really want profits or they are fellow hobbyist spreading corals for the right reasons. Thinngs have changed from a few years agao thats for sure.
