Seriously, what difference does it make in regards to how long it takes? Would Tech write better music if he took a year as opposed to six months to work on an album? Impossible to compare. Regardless of the amount of time he takes, it'll still be the music he wants to write and record for the album.
Will the production get better over that period of time? Not likely, because again, Tech is going to pick the beats he likes and wants to record over. He might run into a new producer in that extra 6 months that he likes and decides to work with (that you might end up liking more than say, a David Sanders), but that could very well happen the month after he completes an album he spent a year on as opposed to those 6 months.
Are more collaborations going to happen? Maybe... maybe not. Deadlines are Deadlines. An artist shows interest in doing a verse for him and gets told "We need this in a week," it's on them if they meet that deadline or not, period. Extra time might make the deadline work for the other artist a little better, but that's still no guarantee that it would get done. Hell, look at Everready. There was a four year gap between it and Absolute Power, and yet... where's that Twista verse? Oh, right... he missed the deadline.
Everyone loves to point out that "killer sounds rushed," but I still feel a lot of that stems from the fact he stated on multiple occasions that it was recorded in a short period of time. Had he not done that, I doubt many would even think it "sounded rushed."
