Seems like you have a lot more options to edit vs GUIMiner. BUT and this is a big but, it shows up as a virus. Now GUIMiner also shows up as a virus, but at least that software is tested now, its just falsely flagged.
With so much software going around that steals all kinds of coins, I am being cautious.
Hmm, I'm not sure why it shows up as a virus, but you can look at the source code and compile it if you wish. What it does is automate the creation of .bat files with the options you give it. This may or may not be the reason why.
