Whenever I select a new phone / tablet, I always check benchmarks on
http://www.androidbenchmark.net/Then I check the battery life etc, I'll have a bit of a look into it now for you

Alright I've had a look into it, the samsung has a more powerful cpu(samsung has a 1.2ghz quadcore vs the 1ghz quadcore of the RCA), more ram(by 512mb), a higher quality camera(3.5mp vs 2mp), and a higher resolution screen (1280x800 vs 1024x600).
I'd go for the Samsung
