Precision: When I hand prime, I can feel the primer seat to the bottom of the pocket. I then turn the case 180 degrees and apply the same pressure again. That makes me believe that the primer is seated squarely to the bottom of the primer pocket. I believe that that is what I should be doing for most uniform ignition. At the same time, I use my finger to check that the primer is actually at or below case head level. It always is. Some people believe it makes sense to seat to a uniform depth below case head, regardless of what pressure it takes or of the resulting relationship to the bottom of the primer pocket. I don't, haven't run any tests on their theory, don't intend to.
Safety: Some people think it's not a good idea to stack a bunch of primers in a brass tube, reasoning that if one goes off, they all go off, and you may REALLY wish they hadn't. I agree with them. However, I'm not aware of a lot of mishaps of that nature. Then again, there are lot of things that I'm not aware of. Doesn't mean they didn't happen.
I have heard that there are a lot of satisfied Dillon users. I even know some personally.
Your choice.

Several companies now make hand-held priming tools that are probably also good and may even last longer. Try a couple out at the store and buy the one which feels best to you. Besides, you can sit in front of the TV and watch Oprah and Rosie and all of your other favorites while using the hand tool!
If there is something decent on TV to watch, then I take a bucket of brass down to the living room, along with a good amount of primers. Go to the fridge and get a cold Pepsi, and use the RCBS handprimer tool.
If there is nothing on TV worth watching (which is generally the case) I use either the Rock Chucker or the Big Max to do the priming.
I honestly haven't noticed any difference at all in accuracy of the loads...
