Doing a little research I really found out scattered and unclear informations about the most common governors that we can choose from except the default ones ofc, if you have a detailed wiki list please point it out, here I am listing all the behaviour I see trying each governor, classifying with
red - high performance
yellow - medium
green - low battery usage
for tick I mean clock level.
Scary
Most of the times keeps cpu on the possible lowest level, for single actions it never reach maximum clock, instead increases it of 1-2 ticks, it reaches maximum clock only for long and persistent requests, in the average it would stay between 128 and 384mhz.

Lagfree
On an action request it pumps up the cpu to the maximum or nearly maximum level and gradually scale it down to the minimum, this is a very dinamic governor that gives high response rates but not continuosly due to the fast down scaling.

Interactive
This is a sort of edge governor, it justmps between the maximum and the minimum level every action request, can give slightly better performances than the lagfree, but not in a really noticable way, but can give slightly low battery consumption for the instant clock reduction it has.

smartass
as long as the screen is on it is at maximum cpu clock, reduced on sleep. (i guess :P)

smartass v2
this is a lively governonr, it is somekind of mix between interactive lagfree and smartass, it is like a roller coaster scale up and scale down, but can jump max and jump min, and I guess it has low values under sleep.

InteractiveX
It is like interactive but scales down on sleep.

this is what I get just by looking at how the clock rates move, sorry if the informations might be wrong, this is just how they seem to work for me :)

i think smartassv2 is the best: good performances and very good battery life!
