The PW 2000 and RB21-535 series engines were both offered on the B757. in terms of reliability, maintenance costs, and sfc, does anyone know where each engines stands? and does one have a better resale value over the other for an older 757?

I believe that PW2037 has a better "Brand New" SFC, but that advantage is quickly lost through deterioration.
In terms of reliability, mx costs and on-wing life, I believe that the RB211-535E4 is the hands-down winner.
As an aside, I've often wondered why the Tu204 hasn't picked up more western operators. A comparable aircraft to the B757, but at half the price.

The RR RB-211 series offered on the B-757s do have a much lower maintenance cost and can stay on the wing much longer than the PW engines can. The RRs also have a higher thrust rating.
The PW 2037 and 2040 series offered on the B-757 cost less and have a lower SFC than the RRs. But they also offer less thrust and higher maintenance costs.
Now LCCs that have operated these engines on B-757 models include ATA (RR RB-211s on both the -200 and -300), Song (PW 2040 on the -200), and National (RR RB-211s on the -200). There may be others, but those are the first LCC operators of B-757 models that crossed my mind.
I might add that UPS operates B-757-200PFs with both engines. IIRC the first 20 or so B-757s they bought are equipped with PW-2042s, and the last 20-25 airplanes they bought came with RR RB-211-535E2s.

Does the PW 2000 series have FADEC? I know that the RB-211-535 does not have a FADEC, but has an EEC and a hydromechanical FCU. It is amazing that even without the FADEC, the RB211-535 Mx costs are lower. Where and what are the high Mx cost items of the PW2000?

Quoting Alitalia744 (Reply 9): GE was originally developing an Engine for the 757, I believe AA and AZ were on board at the time.
It was even ordered - I believe by one of the Hawaiian airlines? But I think I read somewhere that it wasn't really optimised for the 757 and neither Boeing nor GE could see much future in it so it was dropped.
