The 20g will flow 48-49 lbs/min, the 50 trim will do 50. About the same power capacity. Spool is similar. Lately I like to avoid hybrids and stick to a solid unit that is ordered directly from the manufacturer, no turbo shop tinkering. I like to go full mitsu or full garret. I'm getting lazy in my old age or something...
The 60-1 shouldn't even be mentioned in the same conversation at 60+ lbs/min
The EVO3 is nearly as good and quite a bit cheaper at ~42-43 lbs/min, but getting 400 on it requires it to be completely maxed out, and tuned to within an inch of its life. If you really want 400 the 50trim/20g will do it a little more comfortably.
