I've never had any fem seeds herm where it wasn't a fuck up of my own doing, seem to be as strong as regs. However, some have been a bit more prone to late flowering nana's, but that's more likely to be strain related than anything else, and even though I like to over mature my buds I've never had any pollination from those late flower nana's, so I've stopped giving a shit unless they were to turn up mid flower.
Autos? Well, that's a bit more tricky to answer, really comes down to the individual and their circumstances. I love them because they are fun, and they all seem to have a nice mellow edge to their stones. But there's also a list of downsides to them, mainly due to lack of control over veg time, which means any minor fuck up can be a major problem. Also having to pay to run lights on veg cycle start to finish is an extra cost. I like to run them as a quick outdoor run in late spring, early summer, and as a way to utilise space and light during longer veg times and other convenient situations, but still spend more time, energy, space, and focus on my photo plants, so I don't grow a lot of autos. Certainly wouldn't want to grow auto's only.
I'd recommend having a bit of a play around with autos on the side so you can figure out what you think of them, and how you can work them into what you are doing.
