It depends on your win rates and how well you multitable. These are not things that other people could know about you.

If you want to make a fair comparison of the stake levels, you can try to choose stakes with the same comfort level, where

comfort = bankroll * win rate / (standard deviation ^2).

One interpretation is that if you stay at the same level without withdrawing (or learning), then your risk of ruin is about e^(-2 * comfort) ~ 1/7^comfort.

For example, if you have 300 BB, and your win rate is 2 BB/100, and your standard deviation is 15 BB/100 (reasonable stats for full ring limit), then your comfort level is 300 * 2 / 225 = 2.67. If you play SNGs with 40 buy-ins and your ROI is 20%, and your standard deviation is 1.7 buy-ins (typical for 9 or 10 player SNGs), then your comfort level is 40 * 0.2 / 2.89 = 2.77. So, the risks of playing those games would be comparable.
