As a sequencer I think Fruity Loops is one of the most underrated sequencers real easy and quick to use but a lot of people who used to tell me it was crap when I started using it were the ones trying to use it stock standard. Once you replace all the samples with your own it's hot.
But you shouldn't be using any sequencer with the stock samples.

All my stuff is made with it.
