gt avalanche 1.0

Hi guys hopfully this will be the last time i ask this but i would like your opinions on which bike is the best out of the gt avalanche 1.0 for £550 or a mongoose tyax super for£400.
These are my final choices there is a big diffrence in price but is the gt worth the extra?

Both are good value at their respective price points, but the 1.0 is a better bike!
Have you tried them? No good if you don't like the fit.
