By larger return do you mean larger variance? If so then yes.

Here is a thought experiment for you. I will give you a 20% LR. You have a choice:
1. You get to bet $100 on the flip of a coin. (No house edge)
2. You get to bet $100 on 1 number straight up on a roulette wheel. (American wheel, house edge %5.26)

Which is better an why?

NOTE - This is really simple math and anyone who can't do this should probably not consider making money at advantage gambling.
