i think you'd probably be ok on sourcing, usually the later works are not as problematic as say very early ones (i.e. bach, mozart, etc.).i just like henle more for their layout, smart page breaks/page turns, paper quality, print type and setting (i.e. large margis, dark defined , etc). i think all these things add up to quality scores meant to last, i mean care for them and they are usually (if a larger volume vs single short works) a 'buy it once for life' deal, so int he long run i think thye are worth the extra cost.if you're concerned with accuracy, etc look for durand, i believe they were the original publishers https://www.sheetmusicplus.com/title/Preludes-Books-1-and-2/5444007.ed peters is prolly pretty good, and if it's all you can afford, i'd also consider the dover sets. i have those and generally they are extremely well made adn accurate (i.e. sewn lay flat bindings, etc). i mean 10 dollars for both sets and again this is a very good inexpensive score, it is the one i used with my music school college piano professor and he never had any issues with it.https://www.amazon.com/Complete-Preludes-Books-Dover-Music/dp/0486259706stay away from kalmus at all costs (unless it is all you can find. i do not have a single kalmus score, i.e. those white cover ones, that i have not had to 'surgically' repair after only a few short months with lots of packing tape etc. to keep pages from falling out all over the place, i mean i literally almost have to re-bind the entire thing.).
Thank you for your insight. I'm now considering Durand, due to their authenticity (and relatively good price, atleast compared to Henle.)
also, for something this nice, i'd consider spending the extra few dollars (i.e. over the internet or music shop in person) and getting a set of plastic urtext protectors, i use these for all my scores i keep inmy bag that i actively work on https://www.sheetmusicplus.com/title/Clear-Vinyl-Cover-The-Original-Urtext-Protector/17633918
