2x leaves at the mercy of margin calls, which inconveniently come at the moment where you least want to sell (right after a huge crash). Getting margin called after a 50% crashes leaves you with $0, as an example.
A 50% market crash would be brutal even without leverage, but at least no one would force you to sell.
