ruah, i've been flying with manual trim 95% of the time over the past couple months.  have flown since 2002 off and on.  from 2002 to 2007, i used combat trim and stall limiter.  i stopped using stall limiter around 2008.  
so much depends on the types of situations we put ourselves in when we fly when it comes to trim.  
if you have a favorite ride, go offline and do some testing.  if you go about it methodically, you'll see some surprising things.
