Hey! I think reviews can be just as highly regarded as original research if you get them published in a decent journal- you only have to look at how often review papers are cited to see how central they are to furthering research. There are even journals devoted purely to review papers. It might vary according to subject of course, but if you've written a good review which is novel and has implications for further research or practice, then I would definitely go for publication. Of course there are different types of reviews as well, such as systematic reviews and reviews based on meta-analysis etc- some might be considered to be more valuable than others. And of course if you are planning to apply for funding at some point then you need to be skilled at reviewing existing literature, so learning to write a quality review paper can stand you in good stead!
