Well, hard to say unless you post prices. Ego8 will be better than a Fusion F8, BUT depending on prices, is it worth it??
As far as purely on how it shoots and quality, all stock, I would rate:
Ego 8 > Ego 7 > Ego 6 > Etek2 > Fusion F8 > Ego 5 > Etek. However price would play a huge factor for me, since the Fusions can be had very inexpensive, and are darned sweet for their price.
