XE6 or XE7 for VCL Development?

XE6 or XE7 for VCL Development? Putting aside mobile and Firemonkey considerations, does anybody have any thoughts on which of XE6 or XE7 is more stable for VCL development? I get the slight impression from various posts that XE6 did a good job of being a "quality" release, but things might have deteriorated slightly with XE7. (I'm pretty sure both of them still suffer from the "out of memory" problem which is a major pain in our current XE5.) 75% of our work is still in VCL so even a small difference in stability could make a lot of difference - we're looking to hopefully stay on the same version for 18-24 months. Looking at the feature list I don't think there's anything too compelling in the VCL side for us.
