Depends on your needs. I typically recommend Instagram noobs to start off with the 3 day free trial version of Instagress and then move on to FollowLiker which has more advanced features. FL offers much more flexibility in terms of settings, which means that you can really fine-tune them according to your requirements. The only advantage that I see to Instagress, is the fact that it can be accessed from any computer, since you access it from your web browser whereas FL is a software that you have to download and install. The other advantage you get from that, is that Instagress will keep running, even if you log out of your account. FL will stop doing what it's doing as soon as you turn off your computer. Last but not least, Instagress is much more user-friendly, I find. The learning curve on FL is a bit steeper, and can take a few days to get the hang of.
