EFT?
I assume you mean ETF or exchange-traded fund.
Universal Stock Futures?
I'll assume you mean Stock index futures.
There are pros and cons to both:
Futures have longer trading hours available, get better tax treatment, have what I consider to be a more "fair" market (all electronic Globex), offer greater leverage and PTD rules don't apply.
ETF's don't have to be rolled over once a quarter (applicable if your a long term trader) and..... and that's about the only advantage I can think of, I'm sure someone else will have something more to add.
