A lot of subjective points, so always different views. The TB after the updates is a decent device, but I liked the display better on the DX2, so guessing the more packed pixels on the D3 looks even better. Not to mention the DX2 and D3 look very good outside, where the TB is hard to read.
As far as the storage, the D3 makes the most sense, since you can hot swap sd cards (can not on TB) and not worry about apps freaking out, because app data is in the internal flash. The DX2 is set up this way too, but pointless since like the TB, the card is stuck behind the battery.
The only thing IMO that the TB has over the D3 is the 4.3" display. LTE is moot for me, since another year before common in my area and the current LTE chips are battery hogs.
D3 has a much faster chipset, better on battery, 9GB more internal storage, HDMI and apparently the best keyboard ever, for a smartphone.
