the difference is 5% bigger aspect ratio on the 75s... i.e. the sidewall is a bigger percentage of the tread width and therefore a little higher. The difference? Maybe a tiny bit on your speedometer, which if already not too great, may be worse.
The 70s may handle a bit better than the 75s, but tire quality and design are a bigger factor. Neither should rub or act different from one or another, should be very interchangable, if you wish.

If your speedometer has been calibrated for 195/70 R 14 tires, replacing them with 195/75 R 14's would result in the speedometer reading low by 3.01%. Same as with the speedometer, if your odometer has been calibrated for 195/70 R 14 tires, replacing them with 195/75 R 14's would result in the odometer reading low by 3.01%.
