Image quality differs e.g.
textless 4 loses vertically but gains horizontally, also zoomed in further resulting in increased detail.
textless 5 is more censored, lower res, but much reduced artifacting which retains certain details better.

tl;dr different cropping/res but overall the textless version retains detail much better than the text release.

せっかくなので・・・アスナはＮＴＲがよく似合いますね。ＳＡＯは２次創作描きやすそう。ゲーム内空間って設定にしておけば何でもできそうですし。
