Yeah, this, for sure.
I actually played both, but SotFS I played entirely in co-op with @ShivaX and playing DS in co-op mode is very much easier than playing solo, and since Dark Souls 2 SotFS overall made co-oping with a friend a lot easier (possible) over DS1 that’s probably why I felt it was easier. Though I did beat DS2 vanilla at launch by myself (I mean, I summoned NPC’s and the odd random player of course, but didn’t play through with Shiva that first time) and still found it overall a better and more level experience than DS1. SotFS was a big jump in difficulty, and I don’t know if I could have solo’d that (I mean, I guess eventually, but would I before I got frustrated and gave up, having already beaten in twice at that point…? Probably not.)
Speaking of, does anyone know if they are keeping the same co-op (completely random) in Dark Souls remastered, or going to a more Dark Souls 3 model where you and a friend can just have the same password and “friends only” options set in the menu? I want this on PC if I can co-op it with Shiva (at last) but if that’s not the case, I’m curious about getting this on the Switch.
