there is no comparision btw revo / fortuner with sportage ... spotage is different league its not a proper suv... it comes with own benefits such as smaller size , comfort and fully packed with features ... where as revo / fortuner are longer in length , got better height clearance and rigid .. will put mind at ease when in rough areas ..
If you are switching from civic you will not like revo/fortuner comfort for sure and after using some time you will also not be satisfied for sure ... unless you are ready to accept it as it is due to its other benefits ...
where as in sportage you will feel more car like with better height clearance and ofcourse better view like mid-suv ( large sizes cross over ) plus panoramic roof gives a slight luxury looks .. its a good change for those who like features...
Revo i think is still not a family car , it should be secondary car in presence of any car we have ... the back trunk space will hardly get used plus rear seats are always not comfy ..
If you will be using for family go for sportage if personal then you can think for revo.
Plus It doesnt matter how many reviews you read the best way to judge is to take test drives of both.
