In all seriousness, no-one really knows what is safest, aside from Jagex of course. A mouse recorder is preferable to botting because it may result in only a macro minor ban, not macro major.
I wouldn't overthink it - just let the recorder run as you would normally play and provided you keep your sessions short, you should be fine. Bans are pretty random though so there are no guarantees!
