Resale HDB Kitchen Without or With Wall Tiles?

I got a Resale 3room, so there is 2 side of wall. I wont install top cabinet, so only has bottom cabinet (the more cabinet, u will put more things!) 

I seldom cook, maybe will like 2-3 per week or even lesser.

I am now decide to do Without or With Wall Tiles..

Had mixed reviews haha.

If i

Put tiles is nice but ex.. but on long run, one day the tiles will also crack. 
Install backsplash but what abt other side of the wall?  The hairline cracks, i think depend what paint u use ba?   (if use paint, must use oil base sealer? i think WATER-BASED SEALERS is better?)
