Try Lightning. Its a bit buggy and unfortunately put tabs at the top (whyyyy ..) but zooming and reflow are like opera mobile assuming you mean the classic one, not the one with random font sizes.

My experience is that Lightning text reflow doesn't work at all like pre Kit Kat Web View text reflow. How have you configured Lightning?

Hm, what exactly are you looking for? I am on 2.3 so maybe it's just using some OS provided stuff, if so, sorry for the useless suggestion. For me it seems similar to what I remember from the stock browser and the good old opera mobile before the drama (rip...).
