The only reason the second has been deemed easier IMO is because of the replenishing health and healing save points. In the first game if you barely made it out of your battle with little health the scarcity of potions and shops made surviving your next battle much harder. This was very evident in the beginning of the game where you fought several boss fights close to one another and is what turned off a lot of people from the game.
The actual enemy encounters in the second game are much harder then the first. I've played every iteration of the game NG/Black/Sigma/NG2. You're fighting usually double the amount of enemies at a time and they are much deadlier and cheaper.
The only thing they added in Sigma over Black was a easier difficulty (which you may have played on) and a few extra save points. They also added the ability to jump and shoot arrows which helps with some of the gun wielding enemies later in the game especially the Tairon grenadiers and RPG enemies.
