Starwood Preferred Guest - Sheraton Heathrow vs. Sheraton Skyline Hotel?

I'm looking at a one-night stay in the London Heathrow area in late June and found great rates at 47GBP for the Sheraton Heathrow and 55GBP for the Sheraton Skyline Hotel.

Which one should I choose?

I'll be departing on BA from Terminal 4 the next morning, if that matters.

Thanks!

I haven't stayed at either but there is an existing 11 page master thread called "Sheraton Heathrow vs. Sheraton Skyline" that may be of assistance to you.
