Yes RefererX is definitely much better than PRStorm. Why? Because PRStrom was meant for spamming while RefererX was meant for Internet marketing. And how is that make any difference? Well by having that in mind RefererX comes with firstly guidelines & techniques to be used, in order for you to get much better conversion rate. Secondly RefererX is capable to promote your links not only to website that uses server base traffic log such as webalizer, awstats, cpanel stats but also to a highly active, responsive, network of feed jit.com through its widget of live traffic feed. None other tool are able to penetrate in this segment.
Promoting links on server base access log alone will not gives you fast results. Wheres by promoting it on feed jit widget you could start seeing traffic coming in as fast as after 30 minutes. (depending on how accurate / targeted your website database is)
FYI RefererX also comes with video tutorials and 3 channels of support (YIM/email/hotline) for you to learn the right techniques that convert well. So now, the option is yours, either you use the same old technique that is slowly ineffective or you choose to move on to the next level of referring technology ONLY through RefererX.
