Siamining is a very simple mining pool to use. It is obviously used to mine siacoins only, but it allows you to do it quickly and without much knowledge.
The only shortcoming for code geeks is the unavailability of source codes for clients. Consequently, it is possible to start quickly but you remain with what you have without the possibility of changing it. Moreover, precisely the lack of source codes does not have the certainty on the part of the community that there are no unhealthy codes behind it.
However, apart from this, as with all pools, if you want to actually see positive margins, you need to have a good ASIC otherwise it becomes useless regardless of the platform you use.
