According to some (old) Justin's post, I was thinking that 1) was the fastest one. In fact, CPU monitoring shows that that fastest one is 2) (Reaper v3.06pre7).
I really don't understand why! If a dev read this post, can he just confirm/say why (very briefly) ?
I think it depends on what condi1 refers to.. If it's mostly 0, then 2) should be faster. Other cases, the difference becomes less I'd think.
