Questions on Spider Farmer SE5000!

Hey guys I just ordered a Spider Farmer SE 5000 for my AC infinity 4x4 tent. I paid 500 flat shipped, But a friend of a friend today told me he has 2 Spider Farmer sf 4000s he would sell me for 450 maybe 400. Before I ordered I had done my research etc, but I heard somewhere that the newer SE models were better for just flowering and the SF models were better if you were verging and flower. is this true and if so can you enlighten me why please? is it spectrum? I voted for the SE model because I figured it would have better more even spread over my canopy compared to the SF series. Should I return the SE and get the two SFs? just looking for some input from you guys.

Also I see a lot of people saying the Alibaba lights with mean well and Samsung drivers are just as good if not sometimes better and cheaper, any truth to this? does anybody have any hands on experience with them to compare?

if you had 500 for LED for 4x4 what would you have done in my shoes?

appreciate any and all input!
thanks guys
