I used x64dbg recently, because I had to debug Win64 code and both Ollydbg and IDA Free don't support it.
I like the x64dbg UI a lot more, I loved the persistent breakpoints and it was just very easy to pick up and work with. I found one shortcoming: it doesn't have an inline memory viewer - but it can export a memory section to a file.
