The difference being that collectibles are optional and usually fill in backstory or enrich the environment/lore. Also they are completely optional. Wave based encounters force the completion of enemy vanquished before allowing player progress. They are not the same, if you have no interest in the environment or story then yeah, ignore everything and complete the game in 5 and a half hours. But then why buy it in the first place?
True, ultimately I think it will depend on each players style of play. Some people will want to explore, while others just want to get through it guns blazing.
