Interesting, as we have had both brands in the past.
We originally bought the Ameri-Lite but traded it back in to the same dealer after the one year warranty was up, it literally required a trip to the dealer for repairs after every outing. Flimsily built with undersized materials and insufficient fasteners. Hopefully they are better now. I would not consider buying another one.
We bought our Springdale in 2007, it initially had a couple issues which I fixed as they were not worth the 30 mile trip back to the dealer, one was a drip under the sink that just needed snugged up, then a couple of pieces of trim popped loose and needed a couple more brads. A couple of years later the bathroom GFI outlet failed. Other than those minor issues it was trouble free. Not a great trailer but a good value and put together as well as could be expected at that price point. I would consider buying another one.
These experiences are from several years ago and may not apply to today's products, but you asked and I felt compelled to respond.
Good luck in whatever you choose.
