Sage Mode is a multiplicative power. You need base jutsu to enhance with it, you need to be good with taijutsu to use it's enhanced strength, and you need speed to use it's sensing.

EMS is an additive power (except in very specific circumstances), as it grants the user abilities that are powerful regardless of the background. In addition stuff like analysis help the user become stronger, but all the strong and skilled people made plenty of their own jutsu.

It's thus hard to say which is superior. It largely depends on your natural power. Though i'd say that EMS is a "safer" bet (IE most likely to benefit a random ninja the most).
