I try to use coreless digitals, because of the repeatable accuracy. Some like metal gears better than nylon, some don't, but I've found the thing I want the most is accurate precision, so I use a good high speed with digital and coreless technology. If I had some spare bucks for throttles right now, I'd go with the new Hitec 7985's. What I have currently is the 5625, and they aren't coreless, and you can tell on the speed. I think throttle is a lot of "personal preference".
Bob,
I couldn't justify the 7985 for a throttle servo with the way I fly. I had some 5645's that didn't center very well, so how would that impact a throttle servo where the end position is what I'd like to see repeatable? As I understand it, the 5625 and 5645 are the same except for gearing. I've got 5985's on my Ultimate that I'm tempted to try on the throttle to see what the difference would be between the cheapy S3004 and a good digital servo.

The response time difference between S3004 (0.19sec) and 5985 (0.13sec) is 0.06sec. Not sure if the difference can be felt on throttle.
The repeatability on end point RPM could be influenced by other factors, such as the pot on the servo is dirty, the gear is worn out, the linkage has play etc.
