I'm not exactly confident, it's more like it's your only choice left if you can't get your antenna above the trees.

The 7778 is very similar to the RCA in performance. Your test that shows the RCA is a little better than the LNA200 matches what I have read. The newer LNA200s don't seem to be as good as the early ones. I think it's because they were redesigned to meet the price point of the big box stores.

Instead of going for more antenna or preamp gain some users with tree problems have switched to a preamp with a lower noise figure for a better SNR. Sort of like when a ship is too tall, don't raise the bridge, lower the river.

MikeBear switched to his Kitztech preamp.
