What to use microformats or schema ?

Question

Microformats

I used to use microformat markup because Since autumn, Yandex began to understand the schema format, which was announced in the summer by Google, Bing and Yahoo, the question arises, what is preferable to use then?

Answer 1

If you are interested in traffic from google, bing, yahu, then a scheme is preferable, if only you can get by with a microformat.

Answer 2

I saw the note a bit late, but I'll still ask a question about microformats and microdata.
There are, for example, microformats hListing and hProduct and microdata for the product. Microdata is handy to use for js, but how to use microdata in css? After all, no one canceled classes and id, or did I miss something?
If you still need to use a class and identifiers, then can you immediately combine microdata and microformats?
