Just looked at the two, me personally would look to the airtec one. Seems more history only things to concern me would be the it say belt kit is this fitted or already applied, also its got 2001- headlights with the indicator still in so who done the wiring??? If the history an changes are documented it can all come down to the drive. The second rs, I've never been a fan of tints on the car an it looks like it may have a rear space kit fitted could have been tuned an returned to standard for the sale. Comes down to quality, history, preferred an ultimately the drive. With the airtec rs there may be more done or again returned to standard apart from this part. The stirring wheel is a good indicator on how hard a life its had. When you do make the choice buy a scanguage best product € for € an peace of mind best thing I've bought so far for mine.
