Both coins try to solve a different problem so you're comparing apples to oranges in my opinion. Eth is pretty questionable right now with its community being divided but Bitcoin has withstood all since time 
Yes. I think it will take some time for the Ethereum to prove itself in the wake of the recent DAO attacks.
Not only that, Eth would be alot more useful if it was intended as a currency, not a fuel for a block chain. While eth has value that can be traded for things, that was not the reason why it was made. It was made to fuel these world changing "smart contracts". So from my perspective, if you aren't about to write some smart contracts, this may not be your cup of tea. From a speculation standpoint, is too risky ATM. The protocol is the current laughingstock of the finance world, and the amateur investors that still have a dog in the fight are too responsive to fud/hype. Weak hands
it plagues this sector.
