My first experience with HT was on my dual P4 xeons. Performance with HT on was noticeably terrible. It felt like a dog and pony show. It was best to keep HT disabled then. I'm not sure when that changed, but I don't remember what I did on my subsequent Core 2 duo system, but I do have HT enabled on my current (8 or 9 year old) i7 3700 and don't notice any slowdowns. Last I looked, I had to look at very specific benchmarks to find measurable differences. Qualitatively, I don't feel a slow down, either, so I keep it enabled.
