Radare, in my opinion, is mostly lacking on the user-experience sides. IDA is easier to pick-up and use. Also, I feel Radare's decompilers don't fare as-well as Hex-Rays. I equate this to Windbg - your best Windows debugger, which unfortunately is relatively tough to pick up (I'd argue, mostly due to poor UI choices). Forgoing that, Radare is absolutely packing.
I've moved on to reverse most of my projects with Radare. I'm still missing a handful of small features/plugins from IDA, but it's not a big issue.
