I just started reloading in June with the LnL AP, and have loaded about 2,000 rounds so far. I do not use a case or bullet feeder.
I have never used a Dillon, so I can't speak about how they compare. I can tell you that I've been very happy with the LnL so far. I've had a couple of issues, but they were ultimately user error. I've only loaded 9mm, so I can't speak to loading rifle. FWIW, I run the Hornady dies, and an RCBS lock-out die. If you have any specific questions, feel free to PM me.
I don't think you can go wrong either way, though I'm pretty sure you will find more supporters of the Dillon. For what I'm doing, and based on my research, the LnL seemed like a good fit, and has been just that.
Also, just a heads-up, in the last few months Hornady has made a slight tweak to the primer system. So take issues you might read about with a grain of salt if they're a few months old.
