i remember that someone from the list wrote that using [expr] or [expr~] consumes more cpu than doing the equivalent with 'conventional' objs. but i can't remember the reason and how much the difference is. maybe you'll find it by searching the archive.
I remember that a long time ago, on a Pentium 566Mhz I found that the combination of [expr~] and regular pd operators was the most efficient solution to complex equasions. YMMV, but I think that only experimentation will give the best results. On my AthlonXP 2400 the difference between the 2 approaches was negligible (in that particular case).
I didn't do any extensive benchmarking, but I suppose, that the difference will not really matter, and if it does, only benchmarking your actual patches will give the solution.
But in any way, the expr-family of objects is much faster when it comes to do the patching itself and can be a major time saver. I would encourage anyone to use them a lot. Something like:
expr if ( $f1 > 0, 1/$f1, pow($f1, 2) )
might look a bit scary at first, but if you do this as single objects, it is really longwinded.
