Flat roof- EPDM RUBBER ROOF or Modified Bitumen?

Hi BP Community,  I just purchased a foreclosure in Walton, Upstate NY as a getaway from NYC and while I knew the roof needed to be fixed, I just found out that some areas of the roof need to be entirely replaced as they have a very low pitch and currently have shingles (Not sure why they did that in the first place).  This is all new to me, so I am learning as I go.   My question is - Do I go for the EPDM rubber roof or the GAF self-adhesive Modified Bitumen roof option? So far I got two contractors and one prefers rubber and the other mod bit. Both seem to make compelling arguments, so it's hard to make a decision and the more I research online the more confused I am since I have found articles and videos suggesting one over the other.    I would REALLY appreciate some feedback as I have NO CLUE.   Thanks!  Leandro
