"Good as" is something that is determined in the eyes of the beholder. If an actual threesome produces guilt and shame, then the overall experience with toys would be much better than the overall experience with other people. Definitely, there are sensations that other people can produce that toys can't, otherwise no one would bother with threesomes. However, toys definitely avoid the complications that go with those activities. I guess my question is "What is the reason not to try the toys?" There's no risk of disease, jealousy, or conflict with other partners, so if that enhances your mutual satisfaction, I don't see a reason not too.
