S-Works Tarmac Stack & Reach Help

Hey guys,
I am hoping for some advice on comparing a few different bikes. Am I right in saying that I should ignore top tube length as when looked at without considering seat tube angle mis dimension can be misleading. To get a more practical idea of what my position will be I should be comparing stack & reach therefore?
The bike I am considering is a 2015 Specialized S-Works Tarmac in either a 56cm or 58cm (note I am 187cm tall, 79kg, 78.3cm bb venter-saddle top), flexible, have put in 7000km so far this year).
Currently I have 2 bikes & happy with fit on both:
Scott CR1SL (2012) 58cm
Stack 603mm (no spacers under stem & could comfortably drop 1-2cm further tomorrow).
Reach 394mm + 110mm stem= 504mm
Canyon Inflite AL (2014) 58cm
Stack 590mm (ride with 25mm of spacers as that is how the bike came set up & it's my winter bike)
Reach 388mm + 120mm stem= 508mm
& now it is between the 2 sizes of Tarmac I need help with:
Specialized S-Works Tarmac (2015) 56cm
Stack 564mm
Reach 395mm + 110mm stem= 505mm
58cm
Stack 591mm
Reach 402 + 100mm stem= 502mm
So, when you look at it I could ride the 58cm with the stem slammed & a 100m stem (is that so short as to muck up the handling)
or
Ride the 56cm but with probably 2cm of spacers under the stem.
Thoughts?
Cheers!!
