You can probably save atleast $30-40 dollars if you go with the 414M2. I always see 414M2's going for around 259, while the Xray goes from $310-340 or higher.
I'd go with the Tamiya just because they are a much more experienced company, and there design shows it (IFMAR world Title with the 414M2), while the Evo 2 is still growing in potential.
Both are very tunable cars, and both have there Eye-Candy. Other than my personal preference, I say you can't go wrong with either.
G'luck!
