I don't think GC is an issue, pauses would usually not even be noticed by the user. In terms of speed, as long as you don't choose Python I think you'll be fine. I do think in terms of productivity, something like F#, that has GC, ML style syntax with piping and partial application, and a strict enough type system with Hindley-Milner type inference, would be the most productive. My hold up was mostly with the sentence I quoted which seems to contradict itself.
