As my father used to say "it is a poor tradesman who blames his tools for a lack of quality in his work"
Essentially, we don't always get to choose the tools we use, so we need to know how to get the best out of them regardless of what the general opinion of them may be.
Their Limiter may well be a joke by others standards (but then that standard may also be a joke to others still) but you can program it to perform better than it does out of the box - that is what is being asked by the OP, how can I get the best out of the tools available in reason 5? So, let's answer that question rather than saying buy something else.
