It's not a debate because it's not debatable. It's the way shooters have been since 1978.
Although I solely agree with you on scoreplay being harder overall, I still want to note nobody claimed survival play as better or harder than score play. Both have their difficulties.
As for what you said based on how score plays are build of survival plays with adaptions for scoring, this still greatly differs per game in which you want to use up more resources in one than in the other. Although I do agree that you want to survival consistently with those resources; use them in an exact route, it must be noted that the approach, even if using a survival route, generally tends to still differ. Must be noted that some things are a bit easier to score than to survive as well (I found LLS EX to be easier to score in than to aim for NMNB personally, to give an example.)
As for how survival play tends to be more dominant than score play (which seems like it if I look at the majority of the achievements here; what people tend to aim for in general in other places as well.) I think it generally comes forth from the general idea that survival runs are a bit more simplistic to execute overall (think standard 1ccs here for more simplistic; know that certain survival challenges can at times be harder than scoring in certain games and difficulties in those) as well as that scoring approaches generally aren't known, as far as I know people at some point, if they continue to play, will put some interest in the scoring aspect as well. By for example looking at scoring runs; trying to adapt certain strategies for example.
Mainly saying that scoring usually takes place after a while when the player in question feels confident with the idea of trying it out; thus leading to survival play being more dominant in terms of how runs tend to go, I don't see why this really has to matter either, personally I am fine with people aiming for what they want, whenever they want. As long as they put in their effort, needs to be noted but this thread is also not either survival or score restricted, so people will post about both kinds of achievements.
Also in case I get a reply, if it's gonna be a shitpost I guess that I will not reply.
