Generally tuning the garbage collector is a waste of time. Just follow someone else's recommendation and use that.
The problem with tuning is that workloads change then you have to tune again and again. New garbage collectors come out and you have to tune again and again. Someone at your company reads a blog about some new jvm and its awesomeness and you tune again and again, cassandra adds off heap caching you tune again and again. All this work takes a lot of time and usually results in negligible returns. Garbage collectors and tuning is not magic bullets.
