I've received good elite treatment (Plat) at both the Marriott and Skyline (never stayed at the Renaissance so can't comment). I book the lowest level room and I've always gotten an upgrade at both hotels - but never a suite. My room preferences have always been honored at both hotels (away from elevator).
As for transportation to the city, neither hotel is awesome. I take the free bus back to Heathrow Central, and then Tube/Heathrow Express/Heathrow Connect to central London.

For my dates:
Renaissance is GBP 72
Sheraton Skyline is GBP 80
Marriott Heathrow is GBP 114
Sheraton Heathrow is GBP 73
Moxy Heathrow is GBP 68
If Skyline has a nice pool etc then I'd be tempted to use that. Which one is also more convenient for taking public transport into the city?
I hold Plat so elite treatment also relevant to the equation.
