My sister asked me about these, and whether she could use both of them. Since I don't use about or know anything about either, I bring it to my favorite answer place.
But from what I gather, they're both about the same type of app right? And if so, which one would you all suggest.

I use shortcutme. Very useful. For example I hit my space bar/convenience bar and a letter/key and it will go directly to an e-mail/PIN/SMS of a person or app I designated. Very handy and I highly recommend it.

I've never used ShortCutMe, but I have QuickLaunch and love it. Lots of great features like Akosnitzky mentioned. Plus you can use it to take screen shots, configure various system utilities, etc.

I use it all the time and imho, it makes everything much easier. Very well worth the few $$, but there's a trial if I remember correctly.
