Demon's Souls > Gaiden series in terms of difficulty.

Not really.

Demon's Souls isn't hard, the issue is that it has the most steep learning curve of every game.

But once you have played the game for a while there is a strat that works for each enemy and you don't have to be flawless while executing that strat to beat the enemy...

 

In Ninja Gaiden you have to find the strat for the given opponent and then you have to be flawless while executing it. You can know what to do against a given foe and still fail executing...
