here are my thoughts on both of them...
Senuke does a few things that are different from magic submitter. I tested it on a site for one month, using senuke the smart way for one month. Not as much content was indexed as much as i'd like, however it did work to raise my ranks. I like that you can have many threads going with senuke, so it operates very quickly at times. I like that you can create forum backlinks relatively fast, and easy. all and all, it's a good tool. also like the URL manager that makes copying links and creating link structures very easy.
Magic submitter is perhaps one of my favorite tools. I used it one month on another site. The amount of content indexed and success rate of the software was staggering. for example after one month of use of senuke, every day, and one month of magic, every day, the amount of content indexed on magic was almost 50% higher than senuke. My ranks raised about the same amount, with about the same amount of competition as the senuke project. Magic adds micro blogs, wordpress blog network, PDF sharing sites, and PRess release sites to it's arsenal, and is updated more than senuke as far as adding new sites. The other cool thing (which i have not tried yet) is you can add an unltimited amount of your own sites into the software. requires some programing that i don't feel like messing with to be honest, however the instructions are there. and of course the number one cool thing is it's $67 instead of $127.
so all in all, i'm seriously considering dropping senuke, but i haven't made up my mind yet.
the other thing is, there are other similar softwares i'm looking into. one of them is steve hawkins software from here on the forum. it gets great reviews and it's a one time price.
i'd like to hear from people who use both senuke and magic, or one or the other. what's your thoughts.
thanks for reading and happy holidays.
