what is better for low noise,ripple and high efficiency
forward or flyback
 

It depends upon the current and voltage requirements but, in general, a forward type converter would have lower noise, ripple, and (perhaps) better efficiency. The forward converter is also usually a more complicated design.

whatever the input current waveform shape of a forward converter, you can make a flyback with that same shaped input wavefrom.

so from the input its exactly the same.

They are indeed the same.......maybe at the secondary the forward can have a bit lower peak current peak.

But two transistor forward and two transistor flyback are both applicable where the other one is.
 

but how to control 2 switch forward with pwm designet for single switch
if i use a transformer or some logic, or single switch forward?
also for high power, low noise 100v 25a what topology should i use
and if i filter it with 2 differential filters, i should get very low noise (<800uV i hope)
