I can't compare them, as I've never turned on the Sweet 16. I will say I have no reason to even begin to regret going with the AB. As with everything, it depends on what you want the tool to do, I suppose. I'm not sure in what way the Sweet 16 might be superior beyond price and perhaps portability. If you're a pen turner either is undoubtedly overkill, though I've made quite a few nice pens on my AB. I can also core out 24" bowls that I have no use for but have a lot of fun making. I have not yet found, and don't really expect to find, any use for which the AB is inadequate to my skills and needs. For better or worse, I'm at the point where I can't really plan on future upgrades of tools so I just get things that I think will exceed my needs and skills for as long as I'll be able to use them. It's a fortunate position to be in.
