Portability go for the Retina with 2.7 CPU, looking to save some 2.7 standard MBP, upgrade the RAM and HDD/SSD (or combo of both) yourself. For serious video work the 2.7 will be a benefit, specifically if your software can take advantage of the additional L3 cache.
FWIW i have a Late 2011 15" 2.4 i7 and Base Retina, neither have been any issue. The only concern is if the software you plan to use is updated for Retina, either ways i would expect that you are already using external displays.
If you search you will find a few poles and albeit a small segment of the population the vast majority of Retina owners are satisfied, as ever those with issue and "Haters" will always make the most noise, as has been stated by AnandTech the Retina is the best computer Apple have ever produced, it may not be perfect, then what is
In your shoes i would go for 2.7, 16, 512/768
As the individual you must filter the content of the internet very carefully, everyone is a "Pro", everyone the "expert", for the most part they are not, some are well informed, most far from it . If you need help to make a significant purchase, or qualification on hardware, wait for a recognised source, not the kid with 10 minutes hands on in Best Buy

Would a base 15" be better than a base retina with the 16 gigs of ram? I would put 16 gigs in either way.
Be mindful the GPU on the base 2.3 Unibody only has 512Gb of RAM, the higher tier 2.6 has 1GB, all Retina`s have 1GB. This may or may not have significant impact on your usage, for video editing you are going to want as much RAM as possible both system and GPU.
